A pool party outfit needs to work in three places: in the water, beside the pool, and wherever everyone gathers for food and drinks. That makes it different from an ordinary summer outfit. A linen shirt might look great when you arrive, but you’ll want somewhere dry to put it before jumping in.
The right combination depends on whether you’re attending a backyard barbecue with a pool, a resort gathering, or a birthday party where swimming is optional.
Here’s what to wear to a pool party, with outfit ideas for women and men and practical tips for staying comfortable around water.
First, Decide Whether You’re Actually Swimming
This is the most useful question to answer before getting dressed.
At a casual backyard party, guests might spend the afternoon swimming and moving between the pool and patio. At a hotel pool party, the emphasis may be on lounging and socializing, with fewer people getting into the water.
If you plan to swim, wear proper swimwear beneath a cover-up or change into it when you arrive. If you don’t, breathable summer clothes may be perfectly appropriate.
I’d still bring swimwear if the invitation is vague and swimming is a possibility. It’s easier to leave a swimsuit in your bag than spend the afternoon wishing you’d packed one.
Check the venue’s rules, too. Some hotel and resort pools require appropriate swimwear and may restrict certain clothing in the water.
What Women Should Wear to a Pool Party
For women, start with swimwear that stays comfortable when you’re walking, sitting, and swimming. Then add a cover-up that makes it easy to move between the pool and other areas.
Three Outfit Combinations
For a backyard pool party: A simple one-piece swimsuit, cotton gauze button-down, rubber slides, and a canvas tote.
For a resort gathering: A high-waisted bikini, linen-blend wide-leg cover-up trousers, a matching open shirt, and flat leather-look sandals.
For a poolside birthday: A solid-color swimsuit beneath a lightweight wrap dress, comfortable sandals, and a small woven bag.
A sarong is useful if you want something compact that dries relatively quickly. A loose cotton shirt offers more coverage when you’re eating or sitting away from the pool.
I’d choose a cover-up that’s easy to put on over slightly damp swimwear. A fitted jersey dress can cling awkwardly, while a loose button-down or wrap skirt takes seconds to throw on.
Swimwear Fit Matters
One-piece swimsuits, bikinis, tankinis, and two-piece sets can all work. Choose the style that suits your plans and coverage preferences.
If you’ll be swimming or playing pool games, test whether the straps and waistband stay secure when you bend and move.
For a mostly social event, you have more flexibility with decorative details, but avoid anything that digs in after an hour of sitting.
What Men Should Wear to a Pool Party
For men, well-fitting swim trunks are the easiest starting point. A mid-thigh or just-above-the-knee length is versatile, although longer and shorter cuts are fine if you prefer them.
Choose trunks with a comfortable waistband and fabric designed for swimming.
Outfit Ideas
Backyard party: Navy swim trunks, a white cotton T-shirt, rubber slides, and sunglasses.
Resort pool party: Olive swim shorts, an open short-sleeve linen shirt, and simple sandals.
Poolside gathering without swimming: Tailored linen-blend shorts, a textured cotton polo, and casual slip-on shoes.
I’d avoid relying on ordinary chino shorts as swimwear. They can become heavy when wet and take much longer to dry than proper swim trunks.
If you’re wearing a button-down over your trunks, choose a relaxed fit so it’s easy to remove and put back on.
Choose Shoes That Can Handle Wet Ground
Pool decks can be slippery, so footwear should be practical before it is decorative.
Rubber slides, water-friendly sandals, and flip-flops with good traction are useful choices. For a dressier resort setting, consider flat sandals with secure straps and soles suitable for wet surfaces.
I’d skip espadrilles if you’re planning to spend the afternoon close to the water. Their woven soles and fabric uppers aren’t ideal for repeated splashes.
Heavy sneakers, delicate suede shoes, and high heels are similarly inconvenient around a pool.
If you’ll be walking through a hotel lobby or restaurant, check whether the venue requires footwear beyond basic pool slides.
How to Dress for Different Pool Party Settings
Casual Backyard Party
Keep the outfit simple: swimwear, a cotton cover-up or T-shirt, and water-friendly sandals.
A lightweight tote is useful for carrying a towel, sunscreen, and a dry change of clothes.
If the party includes a barbecue, choose a cover-up you’re comfortable wearing while sitting at the table.
Hotel or Resort Pool Party
A coordinated cover-up can make swimwear feel more dressed up without sacrificing practicality.
Women might wear a matching linen-blend shirt and trousers over a swimsuit. Men can pair solid swim shorts with a relaxed camp-collar shirt.
Check the venue’s dress code if the event includes access to a restaurant or lounge.
Evening Pool Party
Evenings can become cool once you’re out of the water.
Bring a dry shirt, lightweight sweater, or loose trousers. A damp swimsuit beneath a thin cover-up won’t provide much warmth after sunset.
If swimming isn’t part of the plan, a relaxed summer dress or polo with tailored shorts may make more sense than arriving in swimwear.
The Pool Party Bag: What I’d Actually Pack
A few practical items make a bigger difference than extra accessories.
- A towel, unless the venue provides one
- Water-resistant sunscreen and sunglasses
- A dry change of underwear or clothes
- A waterproof pouch for your phone and keys
- A bag for damp swimwear
I’d pack a separate dry T-shirt or dress rather than assuming my cover-up will stay dry all afternoon. It’s especially useful if you’re going somewhere afterward.
Choose a bag with a wipe-clean lining or use a waterproof pouch inside a canvas tote. A delicate leather handbag isn’t the best choice beside a pool.
Fabrics and Accessories Worth Considering
Swimwear made from nylon or polyester blends with elastane is designed to stretch and dry more efficiently than everyday cotton clothing.
For cover-ups, lightweight cotton gauze and loose linen are breathable, although they can remain damp after direct contact with wet swimwear.
Keep jewelry simple. Chlorinated water can affect some metals and finishes, and loose necklaces or bracelets can get in the way when swimming.
I’d leave valuable jewelry at home rather than worrying about where to store it while I’m in the pool.
A wide-brimmed hat and sunglasses are useful for shade, but they don’t replace sunscreen.
What Not to Wear to a Pool Party
The main things to avoid are items that become uncomfortable, damaged, or unsafe around water.
Reconsider:
- Heavy denim or thick fabrics if you’ll be swimming
- Shoes with slippery soles
- Delicate accessories you don’t want to get wet
- Ordinary shorts or underwear worn as swimwear where prohibited
- Cover-ups that are difficult to remove or put on when damp
There’s no need to dress elaborately for a casual pool party. A well-fitting swimsuit, practical sandals, and a good cover-up usually provide everything you need.
Final Thoughts
Knowing what to wear to a pool party starts with deciding whether you’ll swim and understanding the venue.
For women, comfortable swimwear with a loose shirt, sarong, or wrap dress is a dependable combination. For men, swim trunks with a cotton T-shirt or linen shirt work well for most casual gatherings.
Choose shoes with traction, bring something dry to change into, and keep valuables protected.
The best pool party outfit is one that lets you move easily between the water, lounge chairs, and food table without having to think about your clothes.
