“Dress code: Smart casual.” or “Cocktail”

Okay, but what does that actually mean?

One minute, you’re excited about the party. The next, you’re staring at your wardrobe wondering if your favourite jeans are acceptable, whether that dress is too dressy, and how everyone else seems to know exactly what to wear.

We get it. Party dress codes can feel like a secret language everyone learned except you.

The good news? Getting dressed for an occasion doesn’t have to mean buying a whole new outfit or following a list of rules that make you feel like someone else. It’s about understanding the vibe, choosing pieces that work for the occasion, and putting together a look you feel good in.

Whether you’re heading to a formal gala, a friend's wedding, a festive dinner, or a beachside celebration, here’s your guide to decoding the most common party dress codes — with outfit ideas that make getting ready a little less stressful and a lot more fun.

1. Black Tie: Your Main-Character Evening

Get the vibe: Formal, elegant, and a little extra—in the best way.

A black-tie invitation is your cue to bring out the eveningwear. Think sophisticated silhouettes, elevated fabrics, and accessories that make the whole look feel intentional. You don’t need to look like you’re walking the Oscars red carpet, but this is one occasion where dressing up is very much the assignment.

What to wear to a black-tie party

A floor-length gown is the classic choice, but it’s not your only option. A beautifully tailored maxi dress, an elegant column silhouette, or a refined evening dress can work just as well. Look for fabrics with a little movement or dimension, such as satin, chiffon, or velvet.

When it comes to color, black is timeless, jewel tones feel luxurious, and softer neutrals can look just as polished. Choose what complements your personal style rather than what you think formalwear is supposed to look like.

Finish with an evening bag, delicate metallic accessories, and heels or dressy flats that you can comfortably wear throughout the night. Statement earrings can do the heavy lifting, so you can keep the necklace simple.

The LB take: Formal doesn’t have to mean uncomfortable. Choose a silhouette that lets you sit, walk, and enjoy the evening without constantly adjusting your outfit. Looking elegant is lovely. Actually enjoying the party is the point.

2. Other option for black tie: Dressed up, but no pressure

Vibe: Formal, but with a little more flexibility.

The word “optional” is doing a lot of work here. Black tie optional means you can wear traditional black-tie attire, but you don’t necessarily have to go all out with a tuxedo or floor-length gown.

Think polished eveningwear that feels appropriate for a special occasion without being overly elaborate.

What to wear for another black tie event

A floor-length dress is still a great choice, but a sophisticated midi dress or an elevated cocktail dress can work beautifully, too. Look for clean lines, considered details, and fabrics that feel a little more special than your everyday wardrobe.

A satin midi dress with pointed-toe heels, for example, can look effortlessly refined. Add a structured clutch and understated jewellery, and you’re ready.

The LB take: When in doubt, it’s usually easier to start slightly more formal and adjust from there. You don’t need to compete with the dressiest person in the room. You just want to feel like you understood the assignment.

3. Cocktail Attire: A Little Glamour Goes a Long Way

Get the vibe: Dressy, celebratory, and ready for a good time.

Cocktail attire is one of the most versatile party dress codes. It’s dressier than smart casual but generally less formal than black tie. Think wedding receptions, engagement parties, milestone birthdays, and dinners that call for something beyond your everyday workwear.

This is also your chance to have fun with colour, texture, and accessories.

What to wear to a cocktail party

A cocktail dress is the obvious starting point, but you have options. A tailored jumpsuit, a chic co-ord/matching set, or a polished top paired with dressy trousers can work just as well, depending on the event.

A little black dress is a classic for a reason. But if you’re in the mood for something different, consider a rich burgundy, deep green, soft pink, or a subtle metallic finish.

For a daytime celebration, lighter colours and softer fabrics can feel fresh. For an evening event, a sleek silhouette, satin finish, or statement accessory can add that extra touch.

Finish with dressy sandals, pumps, or elegant flats. A compact bag and a pair of earrings can pull the whole look together without requiring much else.

The LB take: Cocktail attire is about looking considered, not looking expensive. You can absolutely rewear a dress from your last wedding invitation. Change the shoes, switch up your jewellery, or style it with a different bag. Same dress, different energy.

4. Festive Attire: Because Celebrations Should Feel Like Celebrations

Get the vibe: Joyful, expressive, and just a little sparkly.

Festive attire is common at year-end parties, holiday dinners, company celebrations, and occasions where the host wants everyone to embrace the spirit of the event.

Unlike some dress codes, festive attire gives you plenty of room to interpret the theme. You can go glamorous, playful, colourful, or understated. The goal is to look like you’re part of the celebration.

What to wear to a festive event

Sequins, metallic accents, velvet, satin, and rich colours are all fair game. Think red, emerald, gold, silver, or whatever colour makes you feel ready to celebrate.

Not into glitter? No problem. A sleek black dress with gold earrings, a jewel-toned blouse with tailored trousers, or a statement skirt with a simple top can feel equally festive.

If the invitation mentions a specific theme, use it as inspiration rather than a shopping checklist. A touch of sparkle or a colour that nods to the occasion may be all you need.

The LB take: You don’t have to wear sequins to prove you’re having fun. If your personal style is more minimalist, let the accessories do the talking. If you love a statement look, this is your moment. Dress for the celebration, not someone else’s Pinterest board.

5. Smart Casual: The Dress Code That Started This Conversation

Get the vibe: Put-together, comfortable, and not trying too hard.

Ah, smart casual. The dress code that somehow manages to be both incredibly common and wildly confusing.

Does it mean jeans are allowed? Can you wear sneakers? Is a dress too formal? The answer depends on the venue, the occasion, and how the pieces come together.

A useful rule of thumb: start with something relaxed, then add a more polished element to make the outfit feel intentional.

What to wear to a ‘smart casual’ occasion

Dark-wash jeans with a structured blouse and loafers are a great starting point. So are tailored trousers with a fitted knit top, a midi skirt with a refined shirt, or a simple dress paired with a polished bag.

A jumpsuit can also be an easy one-and-done option. Choose a silhouette with some structure, add understated jewelry, and finish with dressy flats, loafers, or low heels.

What about sneakers? Clean, minimal sneakers can work for some smart-casual occasions, especially daytime gatherings and relaxed venues. For an evening event or a more elevated setting, loafers, ballet flats, or dressy sandals may be a safer choice.

The LB take: Smart casual should still feel like you. You don’t need to abandon your favorite pieces to look put-together. It’s about balancing relaxed and refined, not dressing like you’re heading to a job interview when all you want is dinner with friends.

6. Business Attire: Polished, Professional, and Ready for the Room

Get the vibe: Work-appropriate, confident, and refined.

Business attire is common at corporate dinners, formal networking events, company celebrations, and occasions where you’re expected to look professional beyond your usual office outfit.

The trick is to keep things polished without feeling like you’re wearing your Monday-morning uniform to a Friday-night dinner.

What to wear for a business meeting or event

A tailored pantsuit, a structured blazer with matching trousers, or a refined knee-length or midi dress can all work. Neutral colours such as black, navy, grey, and beige are reliable, but you can also introduce colour through a blouse, accessories, or your choice of bag.

For a more feminine take, pair tailored trousers with a soft blouse and pointed-toe flats or heels. A coordinated set can also make getting dressed easier while still looking intentional.

Choose accessories that complement the outfit rather than overwhelm it. A structured bag, simple earrings, and a polished pair of shoes are often all you need.

For business casual variations, tailored trousers with a button-down shirt and blazer may be enough. When the invitation is unclear, consider the venue and the seniority or formality of the occasion.

The LB take: Professional doesn’t have to mean personality-free. A considered silhouette, a colour you love, or an accessory that feels like you can make business attire feel less generic while keeping the overall look appropriate.

7. White Tie: The Most Formal of Them All

Get the vibe: Grand, traditional, and full eveningwear.

If black tie is formal, white tie is its even more formal counterpart. You’re most likely to encounter it at state dinners, traditional balls, or exceptionally formal celebrations.

This is not the occasion for smart casual interpretations. The dress code has specific conventions, so it’s worth checking the invitation and any guidance from the host.

What to wear to a white tie event

A full-length evening gown is the traditional choice. Think elegant silhouettes, luxurious-looking fabrics, and refined accessories. Long gloves may be appropriate for certain traditional white-tie occasions, although expectations vary.

Keep your styling cohesive. A formal clutch, elegant jewellery, and dressy shoes will complement the look without distracting from it.

The LB take: White tie is one dress code where checking the details really matters. If you’ve never attended this kind of event before, don’t be afraid to ask the host for clarification. A little preparation beats a last-minute wardrobe crisis.

8. Beach Party: Relaxed, Breezy, and Ready for the Sun

Get the vibe: effortless, comfortable, and suited to the setting.

Beach parties are a little different from traditional dressy occasions. The environment matters just as much as the dress code. You might be heading to a casual seaside birthday, a resort celebration, or a sunset dinner by the water.

Your outfit should feel relaxed without looking like you’ve come straight from a swim.

What to wear to a beach party

Flowy maxi dresses, breezy sundresses, linen co-ords, and lightweight separates are all great options. Floral prints, tropical-inspired colours, and soft neutrals can complement the setting without feeling overly themed.

For a beachside lunch, try a sleeveless linen top with wide-leg trousers and flat sandals. For a sunset celebration, a flowing midi dress with strappy sandals and a pair of statement earrings can take you from golden hour to dinner.

Choose breathable fabrics and footwear suited to the actual venue. Sandals are great for the beach, but if the event takes place on a terrace or in a resort restaurant, dressier sandals may be more practical than shoes designed for walking on sand.

The LB take: Dressing for the beach is as much about practicality as it is about aesthetics. Check the weather, consider the terrain, and choose pieces you can move in comfortably. Nobody needs to spend the whole party worrying about their shoes sinking into the sand.

9. Costume Party: Your Chance to Have a Little Fun

Get the vibe: Creative, playful, and entirely dependent on the theme.

Costume parties are your opportunity to step outside your everyday style. Maybe the invitation calls for a specific decade, a favourite film, a fictional character, or a colour-themed outfit. Whatever the brief, this is one occasion where creativity matters more than traditional formality.

What to wear to a costume party

Start by checking whether the host has given you a theme. From there, you can go all in with a full costume or create a more subtle interpretation through colours, silhouettes, and accessories.

A vintage-inspired dress can work for a retro theme. A monochrome outfit with a few distinctive accessories might be enough for a character-inspired look. If you're coordinating with friends, decide on the overall direction before putting together individual outfits.

The LB take: You don’t need an elaborate costume to participate. Use what you already own, borrow pieces from friends, or get creative with accessories. The point is to enjoy the theme, not spend a fortune on an outfit you’ll wear once.

Three Things to Check Before Getting Dressed

Now that you know what the dress codes mean, here are a few practical things to consider before settling on your outfit.

1. Read the invitation carefully beyond the dress code.

The venue, time of day, and type of event can tell you a lot. A smart-casual rooftop dinner may call for something different from a smart-casual afternoon gathering. If the host has shared a mood board or specific instructions, use those as your guide.

2. Make comfort as part of the outfit (and make it your prio!)

Can you sit comfortably? Walk between venues? Dance without constantly adjusting your dress? If you’re attending an outdoor event, will the fabric work in the weather? An outfit can look incredible, but it should also let you enjoy the occasion.

3. Shop your wardrobe first.

Before buying something new, see what you already have. A versatile dress can work for multiple occasions with different shoes, bags, and accessories. Tailored trousers can move from business attire to cocktail-adjacent styling with the right top. Sometimes, the outfit you need is already hanging in your wardrobe — it just needs a different point of view.

The Final Word: Dress for the Occasion, but Stay Yourself

Dress codes are useful guidelines, not a test of how fashionable you are.

Black tie might mean a floor-length gown for one person and a beautifully tailored alternative for another. Smart casual might look like jeans and a refined blouse, while festive attire could mean a little sparkle or simply a color that makes you feel good.

The best outfit is one that respects the occasion and lets you feel comfortable being yourself.

So, the next time an invitation lands in your inbox with a dress code that makes you pause, take a breath. Think about the setting, start with pieces you love, and build a look that feels right for you.

Because getting dressed should be part of the fun, not the reason you almost cancel.

Now, go enjoy the party. You’ve got this.
