One Piece Swimsuits

What is a one piece swimsuit

A one piece swimsuit is a single connected suit that covers the torso in one piece, joining the top and bottom so there is no gap at the waist. The one piece swimsuit has been a beach and pool staple for over a century, and it keeps coming back because it smooths the middle, stays put in the water and reads as polished anywhere. Our swimwear edit leans into fresh takes on the classic: ruched fronts, bold cutouts, one shoulder necklines and high cut legs that lengthen the frame.

One piece swimsuit vs bikini

The choice usually comes down to coverage and how you like to shop for size. Here is the quick version.

• One piece vs bikini: a one piece smooths the midsection and gives more coverage, while a bikini lets you mix top and bottom sizes.
• In the water: a one piece stays secure through dives and waves, a bikini cools faster and tans more evenly on hot sand.
• Styling: a one piece doubles as a bodysuit under shorts or a skirt, a bikini pairs quickly with a cover up for a fast change.

If you prefer to mix sizes or want a matching set, browse our bikini sets instead. To see every shape in one place, the full swimwear collection has both.

One piece swimsuits with shorts, explained

Plenty of shoppers search for a one piece swimsuit with shorts, so here is the honest picture of what that means at Fashorio. We carry swim dresses and skirted one pieces with built in shorts, which means the short is sewn inside the suit rather than sold as a separate piece. That built in layer adds coverage across the hips and upper thigh, which many people want for surfing, paddle boarding, water parks or simply feeling more at ease. If full leg coverage is your goal, a swim dress with a built in short is the closest match in this edit.

Who a one piece suits

The honest answer is everyone, because a one piece flatters through its details rather than by body type. A ruched front skims a soft middle, a cutout draws the eye in to the waist, and a one shoulder neckline balances fuller hips. High cut legs lengthen shorter frames, while a scooped or square neckline supports a larger bust. For extended sizes, our plus size edit carries flattering one piece cuts too.

How to style a one piece swimsuit

A one piece is the start of a whole outfit, not just swimwear. Three easy looks to try:

• Beach day: add a woven tote from straw and woven bags and a wide brim hat from our hats for shade and polish.
• Pool to bar: slip on a linen shirt or a sheer piece from cover ups with sandals so the suit becomes an evening base.
• City summer: wear it as a bodysuit under high waist jeans or a skirt, tucked and belted like any top.

Getting the fit right

Swim sizing sits closer to the body than everyday clothing, so measure your bust, waist and hips and check the size guide on each product page before choosing. Our sizing guide walks through how to measure and how to read the charts. If you fall between sizes, size up for comfort through the torso, since a one piece needs enough length to sit smoothly from shoulder to hip without pulling down.
