Party Attire Ideas

It’s always nice to be invited to a party, but it always begs the question: what should I wear? If you’ve been invited to a party and you’re not sure what to wear to it, we’re here to help. 

Below, we break down party attire ideas by dress code, theme, and occasion so you can always look your best. 

What Is Considered Party Attire? 

Party attire can mean a lot of different things, though what should guide you the most is the dress code or theme, if there is one. If the invitation doesn’t list either, take a look at the venue and the time of the event to get a hint on what to wear. 

As for what to avoid wearing, you’ll want to keep it classy, even if the dress code is more casual. Don’t wear anything you wouldn’t wear anywhere else in public (a stained shirt, for instance), and remember to choose an outfit that makes you feel comfortable and confident for socializing. You may also want to avoid overly-formal attire for a casual party, unless you’re looking to make an entrance.

Party Attire Ideas Based on Dress Code 

Below, we dive into outfit ideas for some of the most popular party dress codes. 

Formal Party Attire

When you get invited to a formal party, it’s the perfect chance to break out a full-length gown (or even a ball gown, if it’s a white tie event). 

When you’re choosing a gown, remember that the darker the color, the more formal it is, so for an ultra-formal event, go with black or a very deep color and avoid prints. For formal events that aren’t quite so serious, you can go with a jewel tone. 

Semi Formal Party Attire

The semi formal dress code is a step down from a formal dress code. These parties allow for a printed dress, a shorter hemline, or a pastel color scheme (though depending on the event, you may want to avoid doing more than one of these at once). 

A semi formal party can also be a great place for a jumpsuit or a two-piece set, since there’s a little more room in this dress code for experimentation. 

Casual Party Attire

Even though casual party attire is the most laid-back dress code, it can be one of the more difficult ones to discern. For a casual party, you’ll want to keep the venue in mind; is this a graduation barbecue at a friend’s house, or is this taking place at a country club? 

If the party calls for casual attire but you’re celebrating a milestone or you’re at a more elevated venue, it’s smart to stick with a business casual look so you don’t appear underdressed. If the party is a very casual gathering of friends or family during the summer, you can get away with everyday clothing items like jeans. 

Party Attire Ideas Based on Theme

Theme parties remain popular, and with the rise of virtual mood boards, themes are getting more specific than ever. Here are some of the most popular party themes and outfit ideas to wear to them. 

Color-Related Theme 

For a party centered around a specific color, you’ll want to wear a monochrome outfit of that color. Popular choices include all-white parties and baby showers in pink or blue, but there is a ton of inspiration out there for party themes that include neons, jewel tones, and even metallics. 

You can’t go wrong with a basic cocktail dress for a party like this, but you’ll want to check for any other dress code hints on the invitation; phrases like “masquerade ball” may indicate that it’s more formal. 

Under the Sea Theme

Under the Sea themed parties are pretty straightforward; you’ll want to take inspiration from the ocean, though that doesn’t mean you have to dress like a mermaid. Think flowing fabrics in blues, greens, and even a dash of purple, complete with a bit of shimmer.

Accessorize your look with jewelry featuring shells or other sea creatures to really lean into the theme! 

Backyard Cookout

A backyard cookout is on the more casual side of things. Since these usually take place during the summer, a sundress or romper can be a really effortless way of looking put together while still being comfortable. 

For an extra dose of glamour, try a big sun hat; this has the added bonus of more sun protection during the afternoon hours. 

Awards Season Party

Many people host viewing parties for events like the Oscars. These parties can be a bit on the formal side if the invitation’s dress code calls for it, so feel free to go all out if that’s the case. For a more toned-down gathering, a cocktail dress featuring lots of sparkles or an interesting neckline like a one shoulder dress can be red-carpet worthy. 

When choosing any outfit for this type of party, remember that you’ll likely be sitting for a bit of it, so keep comfort in mind. 

Flapper/Gatsby Themes

These themes both call back to the Roaring ‘20s. For a flapper look, you’ll want to go with something that has fringe. Dresses were the most common for flappers, but you don’t have to stick with that to still be on theme. Fringed co-ords or rompers can still be flapper fabulous. 

As for Gatsby parties, these take the same influences from ‘20s fashion, but you can really lean into the opulence and sparkles and fit right in. 

Throwback Night

The style of outfit that you choose for throwback night will depend on the era listed on the invitation. For 80s-inspired attire, think full skirts and bright neons. For a 90s vibe, you’ll want to zero in on moodier looks. 

Don’t be afraid to do some research beforehand and put together a moodboard of your findings so you can choose a look while still staying true to your personal style. 

Western Theme 

Finally, country music is having a moment right now, and with that comes the popularity of Western parties. You’ll want to think chaps, fringe, vests, flannel, and of course, cowboy boots. 

If your party is a more glamorous take on the Western theme (“Denim and Diamonds” is another popular choice), choose bejeweled or sequined Western pieces. You also can’t go wrong with going against the traditional Western color palette and stunning in a pink cowboy hat! 

Party Attire Ideas Based on Occasion

Some of the most common parties that we get invites to center on a specific occasion on the calendar. For party attire inspiration based on the occasion, check out our list below: 

Halloween Party Attire

Halloween party attire will generally be a Halloween costume. You can either wear the costume you plan on wearing on Halloween itself, an older costume, or put together something new for the party. Don’t be afraid to DIY; some of the most creative costumes can come from your closet! 

If you’re not into Halloween costumes, you can go with a Halloween-inspired look in orange, purple, black, or some combination of those colors. 

Holiday Party Attire

Red, green, or metallics tend to be the most popular color choices for festive holiday parties, and it’s a great excuse to add on the sparkles. 

Unless it’s a formal event, you can’t go wrong with a cocktail dress for most holiday parties. If the shortened hemline makes you nervous for a professional event, a suit in a festive color with a standout blouse can be a great choice. Add some sparkling jewelry, a brooch, or a dazzling pair of shoes to boost the festive vibe. 

New Year's Eve Party

Metallics and black are usually the top color scheme for New Year's Eve parties. You can either choose a metallic that you love, slay in a black dress paired with some gorgeous jewelry, or go with a look that incorporates everything. New Year's Eve is all about decadence, so don’t worry too much about being extra! 

If you don’t vibe with metallics or black and prefer to ring in the new year with an outfit in your favorite color, go for it! 

A Great Outfit Is the First Step to a Great Party

Now that you have an idea for what to wear to your next party, it’s time to start researching! Don’t be afraid to consult your loved ones and do some experimenting; you might end up finding your next favorite piece!
