One Piece Cutout Swimsuits: How to Choose and Wear Them

Quick Answer

Choose a one piece cutout swimsuit by first identifying where you want the cutout to sit—waist, side, or back—and then checking that the suit's straps and coverage stay secure when you move. Prioritize adjustable ties or straps, a lined front, and a size that fits your torso length without pulling. If you're between sizes, size up for comfort and use the adjustable features to tailor the fit.

Why Cutout One-Pieces Are Having a Moment

Cutout swimwear for women solves a common dilemma: you want the streamlined look of a one-piece with a hint of skin, but you don't want to worry about a bikini top shifting. A single cutout—whether at the waist, side, or back—creates a focal point and can visually break up the torso, which many find flattering. The key is choosing a cutout that aligns with your comfort zone and your body's natural lines.

Unlike a solid tank suit, a cutout one-piece has less fabric to distribute tension. That means the fit around the cutout matters more than almost anywhere else. If the suit pulls, the cutout can gape or dig in. Look for styles with adjustable straps or ties so you can fine-tune the fit after you put it on.

How to Choose a Flattering Cutout Placement

The most flattering cutout one-piece is the one that sits where you feel most confident. As a rule of thumb: a high side cutout draws the eye upward and elongates the legs; a front waist cutout creates an hourglass effect; a back cutout adds interest when you turn around. If you're short-black-93e59636e2f632bc34aae000-937273">short-1078fcff75ef0580f1c48d15-937272">short-waisted, a small cutout just below the bust can create definition without cutting your torso in half. If you're long-waisted, a larger side cutout can balance your proportions.

Consider the coverage you need. A cutout swimsuit with a high neck and moderate leg opening offers more security for swimming laps or playing in the waves. A deep plunge cutout with a high-cut leg is better for lounging. Also check the lining: a lined front panel prevents any see-through moments when the suit is wet.

Fit Guide: Getting the Right Size and Adjustments

Swimwear sizing varies by brand, so always check the specific size chart. Measure your bust, waist, and hips, and if your measurements fall between two sizes, choose the larger size—especially for a cutout style, because a too-small suit will pull at the cutout edges. The torso length is another critical measurement: if the suit feels tight from shoulder to crotch, it will ride up. Look for a suit with adjustable straps or a tie back to accommodate a longer or shorter torso.

When you try on the suit, do a movement test: raise your arms, twist your torso, and bend forward. The cutout should stay flat against your skin without gaping or digging. If the straps dig into your shoulders, try loosening them or sizing up. If the leg openings cut into your hips, the suit is too small. Remember that swimwear fabric relaxes slightly in water, so a suit that feels snug but not tight in the dressing room is usually right.

How to Wear a Cutout Swimsuit with Confidence

Once you have the right fit, styling is simple. For a pool day, pair your cutout one-piece with a sheer cover-up or a loose linen shirt and slide sandals. For a beach vacation, add a wide-brim hat and oversized sunglasses. If you want to transition from beach to bar, wrap a sarong around your waist or throw on a pair of denim shorts—the cutout detail still shows through.

Sunscreen is your friend, but be careful around the cutout edges: spray or lotion can stain delicate swimwear fabric. Apply before you put on the suit, and use a stick formula around the edges to avoid transfer. Also, avoid sitting on rough surfaces like concrete or rocks, which can snag the cutout's binding.

Decision Rules for Buying a Cutout One-Piece

• If you want a secure swim for active water days: Choose a cutout one-piece with a high neckline, moderate leg cut, and adjustable straps. Avoid large side cutouts that can shift when you move. Checkpoint: do a swim test in the shower or pool before your trip.
• If you want to accentuate your waist: Look for a front cutout placed just above the natural waist. A small, horizontal cutout creates an hourglass effect without exposing too much. Verdict: this placement is flattering on most body types.
• If you're long-waisted or short-waisted: Long-waisted: choose a larger side cutout to break up the torso. Short-waisted: choose a small cutout below the bust to avoid cutting your torso further. Next step: measure your torso length and compare to the brand's size chart.
• If you're between sizes: Size up. A cutout suit that is too small will pull and gape at the cutout edges. Use adjustable ties or straps to take in the extra fabric. Checkpoint: the suit should feel snug but not tight, with no digging.
