Size Guide
Finding the right swimwear size starts with accurate body measurements. Use the guide below to measure yourself, then compare your measurements with the size chart shown on the individual product page.
Because fit and construction can vary between swimwear styles, we recommend checking the specific size chart for each product before placing your order.
How to Measure
For the most accurate results, wear light clothing or underwear and keep the measuring tape comfortably close to your body without pulling it too tight.
Bust
Measure around the fullest part of your bust, keeping the tape level across your back and comfortably fitted around your body.
Underbust
Measure directly underneath your bust, keeping the tape straight and level around your ribcage.
Waist
Measure around your natural waistline, usually the narrowest part of your torso. Keep the tape comfortable and avoid pulling it tightly.
Hips
Stand with your feet together and measure around the fullest part of your hips and seat, keeping the tape level all the way around.
Choosing Your Size
Once you have your measurements, open the size guide on the product page and compare your bust, waist and hip measurements with the measurements listed for that style.
If different parts of your body fall into different sizes, we generally recommend choosing the size that best accommodates the largest relevant measurement for the style you are purchasing.
For example, if your bust falls within one size but your hips fall within the next size up, a one-piece swimsuit or swim dress may feel more comfortable in the larger size.
Fit Tips by Swimwear Style
Tankinis
Tankinis offer the flexibility of a two-piece design with additional torso coverage. Pay particular attention to your bust measurement when choosing the top and your waist and hip measurements when choosing the bottom.
Swim Dresses
Swim dresses are designed with a more relaxed outer silhouette while the inner swimwear provides support and coverage. Use your bust, waist and hip measurements when selecting your size.
One-Piece Swimsuits
One-piece swimsuits need to accommodate the bust, waist, hips and overall body length. If you are between sizes, consider the measurement that requires the most room.
Swim Bottoms
For swim bottoms, focus primarily on your waist and hip measurements. High-waisted, boyleg and skirted styles may provide different levels of coverage, so please also review the product description and images.
If You Are Between Sizes
If your measurements fall between two sizes, your preferred fit can help guide your choice.
- Choose the larger size if you prefer a little more room or additional comfort and coverage.
- Choose the smaller size only if your measurements remain within the listed range and you prefer a closer fit.
Swimwear should feel secure without excessive tightness, pulling or restriction.
Check the Product-Specific Size Chart
CurvesBeach offers a variety of plus-size swimwear styles from different collections and constructions. Measurements may therefore vary slightly between products.
Always use the Size Guide displayed on the individual product page as the primary reference when selecting your size.
