Bust
Wrap the tape around the fullest part of your bust. Keep your arms relaxed and avoid compressing your chest.

Good fit.
Your way.
Your guide to size, support and coverage.
From your first layer to your next swim.
SIZE & FIT GUIDE
Comfort is personal.
So is your fit.
01 / START HERE
A few measurements.
A better starting point.
Use a soft tape over bare skin or a thin, unpadded layer. Stand naturally and keep the tape level and comfortably snug.
Underbust
Measure around your ribcage directly below your bust, with the tape level across your back.
Waist
Find your natural waist by gently bending to one side. Measure at the crease, breathing normally.
Hips
With your feet together, measure around the fullest part of your hips and seat.
Your measurements, in either unit.
Enter a measurement to convert it. This is a unit converter, not a size recommendation.
Your measurements stay on this page and are not saved or sent.
02 / YOUR FIRST LAYER
Intimates that work with you.
Choose the feel you want, then check the measurements for the exact style. A size label alone is not a fit guarantee.
| Style | Start with | A comfortable fit feels like |
|---|---|---|
| Bras & bralettes | Bust + underbust | A level band, cups that contain the bust and straps that stay in place without digging. |
| Panties & shaping shorts | Waist + hips | A waistband that lies flat and leg openings that allow you to sit and move comfortably. |
| Bodysuits & full-body shapers | Bust + waist + hips | Even support without pulling at the shoulders or crotch. Check torso guidance when provided. |
Support, without the squeeze.
Do not size down to create more compression. Choose the intended support level and follow the style's own size guidance.
Between sizes?
Check which body measurement matters most for the style. If your measurements span sizes, ask us about that item before ordering.
Move before you decide.
A comfortable fit should let you sit, bend and breathe normally. Pain, numbness or restricted breathing are signs the fit is too tight.
03 / FIND YOUR SWIM FEEL
Your swim. Your silhouette.
Start with the neckline you love, the support you prefer and the coverage that feels right. Every body belongs by the water.
Find your top
Triangle & halter
Adjustable ties and an open neckline. Check the strap construction and cup coverage for the support you prefer.
LOOK FOR: ADJUSTABLE TIESUnderwire
A more structured cup shape. Check both band and cup guidance, especially if your top and bottom sizes differ.
LOOK FOR: CUP & BAND FITBandeau
An open-shoulder silhouette. A secure band matters; removable straps can offer another way to wear it.
LOOK FOR: SECURE BANDHigh neck
More coverage at the chest. Review the back, straps and fastening to choose the feel and adjustability you want.
LOOK FOR: FRONT COVERAGEChoose your silhouette
One-piece
A connected silhouette. Compare bust, waist and hip measurements, and check torso fit if you are longer or shorter through the body.
Tankini
A longer swim top with separate bottoms. Check whether the pieces are sold individually or as a set.
High-waisted bottoms
More coverage around the waist. Rise and rear coverage are different features: check both in the product photos.
Swim dress
A skirted silhouette with added coverage. Check the description for the built-in brief and the length of the skirt.
THE COVERAGE CHECK
Less, more, or somewhere between.
Minimal
Less fabric across the seat, often described as cheeky. Compare rear-view photos.
Moderate
A balance of coverage and an open leg line. The cut varies by style.
Fuller
More fabric across the seat. A high leg or high waist does not automatically mean full rear coverage.
04 / MAKE IT PERSONAL
The right chart is the one
for your style.
Sizes vary between designs. Use the size information on the exact product page; do not carry one style's S, M or L across every item.

View product & size detailsNeed a measurement chart?
If a product does not show a body-measurement chart, send us its link before ordering. We can help you check the available sizing information for that specific item.
Ask about my sizeShould I choose the same size in every style?
Not necessarily. Fabric, construction and intended fit differ. Compare your current measurements with the size information for each item.
What if I need different sizes on top and bottom?
Separates may give you more flexibility. For a matching set, check whether both pieces share one size or can be selected independently before ordering.
Do the measurement numbers change between inches and centimeters?
Only the unit changes: 1 inch equals 2.54 centimeters. Measure once and convert the value if the product chart uses a different unit.
