A bikini skirt is one of the easiest ways to feel more covered at the beach without giving up a cute bikini. It also turns your swimsuit into a real outfit, so you can walk from the sand to lunch without changing. But “swim skirt” can mean a few different things, and the type you need depends on whether you want to swim in it, cover up over it, or simply add a fun layer.
This guide explains the main types of bikini skirts, how to wear each one, which styles suit different goals and body shapes, and what to look for before you buy.
Quick answer: A bikini skirt is a short skirt worn with a bikini. It comes in two main forms: a swim skirt with built-in briefs that you can swim in, and a cover-up mini skirt that you wear over your bikini bottoms and take off before you get in the water. For extra coverage choose an A-line or tiered style that sits at the waist; for a casual beach outfit, a matching mini wrap or bubble skirt is the easiest option.
What is a bikini skirt?
A bikini skirt is any short skirt designed to be worn with swimwear. Some are part of the swimsuit itself, and some are a separate layer that goes on top. Knowing the difference matters, because it decides whether you can swim in it.
1. Swim skirt with built-in briefs (skirtini)
This is a swim bottom with a short skirt sewn over a full brief. You wear it instead of regular bikini bottoms and you can swim in it. It is popular with people who want more coverage at the hips and seat while keeping a bikini top.
2. Cover-up mini skirt
A separate skirt you pull on or tie over your bikini bottoms. It is designed for the beach, the pool deck and the walk to lunch rather than for swimming. Because you can slip it off in seconds, you never have to sit in a cold, wet skirt after a swim, a small comfort many swimmers mention.
3. Skirted one piece or swim dress
A one piece swimsuit with a skirt attached at the waist. It offers the most coverage, but it is not a bikini, so you lose the option of mixing pieces.
Why wear a bikini skirt?
- More coverage, your way. A skirt covers the hips and the top of the thighs, which helps if you feel self-conscious in bikini bottoms alone.
- An instant outfit. A matching skirt turns a bikini into a beach look you can wear to a café or a boat trip.
- Easy to remove. A separate skirt comes off before you swim and goes back on when you are dry.
- Balance for your shape. A skirt with volume, like a bubble or tiered style, adds shape to the lower half; a fitted wrap skirt keeps the line slim.
Popular bikini skirt styles
Bubble skirt
A short skirt gathered at the hem so it puffs out softly. It looks playful and adds volume at the hips. The Pink Gingham Bikini Set comes with a matching bubble mini skirt that ties at the waist.
Mini wrap skirt
A short skirt that wraps around and ties at the side, like a small sarong with more shape. It is the most adjustable style, because you choose how tight and how high to tie it. See the Blue Tie Dye Bikini with Mini Skirt or the Seashell Bikini Set with Wrap Skirt.
Tiered ruffle skirt
Layers of ruffles give movement and a flirty look. Tiered skirts are also one of the best choices for extra coverage, because the layers hide the bikini bottom underneath. Try the Leopard Bikini with Tiered Ruffle Skirt, which sits low on the hips and has a long sheer side sash.
Ruched mini skirt
A fitted skirt with gathered fabric that hugs the body. It looks sleek and modern, especially in solid colors. The 4 Piece Bikini Set pairs a ruched mini skirt with a sheer mesh tank, so you get a full outfit in one set.

How to wear a bikini skirt: 5 easy outfits
- Matching set. Wear the bikini and skirt from the same set for the easiest put-together look.
- Add a mesh or knit top. A sheer tank or crochet top over your bikini top makes it café-ready.
- Mix prints. Pair a printed skirt with a solid bikini in one of the print’s colors.
- Dress it up. Add flat sandals, gold hoops and a straw bag for a resort dinner by the pool.
- Layer with a sarong. Tie a long sarong over the skirt for a walk into town. Our guide on how to tie a sarong shows eight easy ways.
Bikini skirt vs swim shorts vs sarong
- Bikini skirt: feminine, quick to put on, and the best match for a bikini set.
- Swim shorts: sportier, and better for active days like paddleboarding or volleyball.
- Sarong: the most versatile, since one piece can be a skirt, a dress or a scarf, but it takes a moment to tie.
What to check before you buy
- Swim or cover-up? Check whether the skirt has built-in briefs or is meant to be worn over bikini bottoms.
- Waist fit. A tie or elastic waist is easiest to adjust. Fixed waists need careful sizing.
- Length. Mini skirts look best with a matching bikini; longer skirts give more coverage.
- Size guide. Many of our sets run small, so check the size guide on each product and choose the larger size if you are in between.
Care tips
Rinse the skirt in cool water after each wear, especially after chlorine or salt water. Hand wash gently, press the water out instead of wringing, and lay it flat to dry in the shade. Wash the skirt with its matching bikini so the colors stay even.
