A swimsuit size guide is most useful when you start with current body measurements and compare them with the exact style you want. Bikini tops, bikini bottoms, one-piece swimsuits and board shorts fit different parts of the body, and the same size label does not guarantee the same fit across every design.

What You Need to Measure for Swimwear

Use a flexible measuring tape and wear lightweight, close-fitting clothing or undergarments. Keep the tape level and comfortably close to the body without pulling it tight enough to compress. Record each measurement in the unit used by the product chart.

• Bust: Measure around the fullest part of the bust while keeping the tape level across the back.
• Natural waist: Measure around the narrowest part of the torso or the point where your body naturally creases when you bend to one side.
• Hips: Stand with your feet together and measure around the fullest part of the hips and seat.
• Torso: For a one-piece, overall torso length and proportion can affect fit even when bust, waist and hip measurements fall in the chart. Use the product’s stated dimensions and ask for clarification when needed.

Measure twice before choosing. If your measurements point to different sizes, prioritize the areas the specific garment must fit and use the product page rather than averaging the numbers.

How to Size a Bikini Top

For a bikini top, begin with the bust measurement and review the closure, straps and coverage style. A comfortable band should stay in place without digging in or riding up. Cups or triangle panels should provide the coverage you want without severe gaping or overflow, and straps should adjust without carrying all of the tension.

DBM’s current triangle styles—including the Women’s Black & Red Bikini Top, Women’s Pink & Black Bikini Top and Nautical Compass Premium Bikini Top—have removable padding and panels that slide along the bottom string. Adjustment changes placement and coverage, but it does not replace choosing an appropriate base size.

The Women’s Skull Print Sport Bikini Top instead uses adjustable shoulder straps, an underbust band and removable cups. Treat its sport construction separately from the triangle tops.

How to Size Bikini Bottoms

Use waist and hip measurements, then consider where the waistband is designed to sit. A classic bottom and a high-waisted bottom may meet the body at different points. The waistband should remain in place without rolling or digging, while the leg openings should feel secure without pinching.

Coordinating colors do not require the same size on top and bottom. Choose each piece independently. Compare classic options such as the Women’s Black & Red Bikini Bottom with the Women’s Skull Print High-Waisted Bikini Bottom when deciding which rise and coverage you prefer.

How to Size a One-Piece Swimsuit

A one-piece must work across bust, waist, hips and torso at the same time. After comparing all listed measurements, check whether the straps sit comfortably, the neckline and leg openings remain in position and the suit allows normal bending and reaching. Excess vertical pulling can indicate that the torso fit is too short, even if the width feels reasonable.

The Women’s Bandana Print One Piece Swimsuit currently offers Small through 4XL and lists adjustable straps, removable cups, full coverage, lining and four-way stretch. Use its own chart rather than the bikini sizing examples.

How to Size Women’s Board Shorts

For board shorts, focus on waist and hip measurements and check the intended rise. Sit, bend and step to assess movement through the seat and thighs. A drawstring can refine the waistband fit, but it should not compensate for shorts that are otherwise too large or restrictive.

The Women’s Premium Black Stretch Board Short lists XS through 4XL, four-way stretch, a drawstring with hook-and-loop fly and a right-leg cargo pocket. Compare its numerical-size, waist and hip information with your measurements.

Use Sizing Examples Carefully

Several DBM swimwear pages include examples pairing a size with a model’s height, weight, waist or bust. These can add context, but they are not a fit guarantee because body proportions and preferred coverage differ. Your current measurements and the construction of the exact garment are more useful than matching only height or weight.

Swimsuit Fit Checks Before Use

• Move your arms, sit, bend and take a few steps to check whether the garment stays positioned.
• Confirm that straps and ties remain secure without painful pressure.
• Check coverage from multiple angles and in the posture or movement you expect.
• Review the store’s current return requirements before removing tags, liners or other original condition elements.

Women’s Swimsuit Size FAQs

Should I use my usual clothing size?

Use it only as a starting reference. Take current measurements and compare them with the exact swimwear chart because size labels and garment construction vary.

Can I choose different sizes for a bikini top and bottom?

Yes. The active DBM bikini separates are individual products. Choose the top from bust and top-construction needs, and choose the bottom from waist, hip, rise and coverage needs.

What if I am between sizes?

Review which body area controls the fit of that garment, how much adjustability it provides and the current product guidance. If the chart does not resolve the choice, contact DBM before ordering.

Does removable padding change the swimsuit size?

Removing a pad can change the feel or shape inside the cup, but it does not change the underlying band, tie or garment dimensions. Select the base size from the product guidance.

Do all DBM swim styles have the same fabric features?

No. Many current pieces use 90% polyester and 10% spandex, but construction and claims vary. UV 50+ is specifically listed on the Skull Print Sport Bikini Top, Skull Print High-Waisted Bikini Bottom and Bandana Print One Piece Swimsuit—not every product.

Where can I compare current styles?
