Getting your swimwear size right matters more than with most clothing — a top that gaps, a bottom that pulls, or a one-piece that cuts in somewhere unexpected isn't something you discover until you're already at the pool. This guide walks through exactly how to measure for Le Club Original swimwear, what numbers correspond to which size, and how to handle the common situation where your top and bottom sizes don't match.
Le Club Original women's swimwear is available in sizes S (US 6), M (US 8), and L (US 10), made from 4-way stretch fabric — recycled polyester-spandex for tops and recycled nylon-spandex for bottoms — that moves and stretches with the body. Because tops and bottoms are sold as separates, you can size each piece independently. The fit guidance below is specific to Le Club's construction. For styling combinations once you've found your size, see our how to mix and match bikini tops and bottoms guide.
What You Need to Measure
Before looking at any size chart, take three measurements. You'll need a soft measuring tape — the kind used for sewing, not a rigid tape measure. Measure over bare skin or thin underwear, not over clothing.
1. Cup size — Le Club Original sizes its swim tops by cup size, not bust circumference. If you know your bra size, use the cup letter (B, C, D) directly. If you don't, measure your bust at the fullest point and your underbust (directly under the bust where a bra band sits), then subtract underbust from bust: a 1" difference = A cup, 2" = B, 3" = C, 4" = D.
2. Natural waist — The narrowest part of your torso, typically above your belly button. Measure snugly but without sucking in. Used for bottoms and one-pieces.
3. Hips (at fullest point) — Stand with feet together and measure around the widest part of your hips and seat, typically 7–9 inches below your natural waist. This is your primary bottom measurement. Do not substitute your waist — it will be too small.
Tip: measure over bare skin, not clothing, using a soft fabric tape measure.
Bikini Top Size Chart
Le Club Original bikini tops are sized by cup size. The collection includes four styles — Triangle Slider (Willow, Liliana, Mila), Scoop Bralette (Olivia), Bandeau (Grace), and Shoulder Tie Underwire (Daisy) — each with slightly different fit considerations noted below the chart.
| Le Club Size | US Size | Cup Size |
|---|---|---|
| S | 6 | B |
| M | 8 | B+/C |
| L | 10 | C+/D |
If you're between sizes: For triangle and bandeau tops, size down — the ties give you adjustment range and a closer fit looks better. For the bralette (Olivia) and underwire (Daisy) styles, size up — structured styles with less adjustability should fit comfortably at their largest point.
Cup size guidance: A size S fits a B cup, M fits B+/C, and L fits C+/D. The Olivia bralette includes removable cups for additional shaping. If your cup is larger than the range for your size, the Daisy Shoulder Tie Underwire Top offers the most structured lift and customized support in the collection.
Bikini Bottom Size Chart
Le Club Original bikini bottoms are sized by hip measurement. Size your bottom independently from your top — it is very common to wear a different size for each.
| Le Club Size | US Size | Hips (at fullest point) | Natural Waist |
|---|---|---|---|
| S | 6 | 37–38" | 26–27" |
| M | 8 | 39–40" | 28–29" |
| L | 10 | 41–42" | 30–31" |
If you're between sizes: For cheeky styles (Ava, Quinn, Layla, Eden), size up — cheeky cuts have less coverage and a slightly small bottom will feel more exposed than intended. For full coverage hipster styles (Ruby), sizing is more forgiving; stay true to size or size up if you prefer more seat coverage.
Style-Specific Fit Notes
Triangle Slider Tops (Willow, Liliana, Mila)
Fully adjustable at neck and back ties. The most size-flexible top in the collection. If you're between sizes, try both — the ties allow a wide range of fit. The triangle shape provides light to moderate support; ideal for smaller to medium busts or for those who prefer minimal coverage.
Scoop Bralette Top (Olivia)
Wide shoulder straps and a rounded scoop neckline. Less adjustable than triangle styles, so accurate sizing matters more here. The Olivia has removable cups for additional shaping. Best for those who want more coverage and a supportive, structured fit without underwire. Recommended for full busts: size up from your triangle size if the Olivia feels tight across the band.
Bandeau Top (Grace)
Strapless, minimal coverage. Best suited for A–C cup sizes where the bandeau will stay in place without straps. The Grace is not recommended as a primary top for larger busts or high-activity days. It excels as a second top rotated in for poolside tanning.
Shoulder Tie Underwire Top (Daisy)
The most structured and supportive top in the Le Club collection. Built-in underwire provides lift and shape; shoulder ties allow height and coverage adjustment. Recommended for D cup and above, or for anyone who wants confident support for an active beach day. The Daisy runs closest to true bra sizing — use your underbust + cup measurement rather than just bust circumference.
Cheeky vs. Full Coverage: Which Sizing Logic Applies?
Le Club bottoms come in two cuts that have slightly different sizing behaviors:
Cheeky cut (Ava, Quinn, Layla, Eden): Higher on the hip with less seat coverage. These bottoms sit higher and feel smaller. If you are right on the border between sizes, we recommend sizing up for a more secure, comfortable fit. A too-small cheeky bottom will ride up and feel restrictive; a slightly larger one will still look intentional and sit correctly on the hip.
Full Coverage Hipster (Ruby): V-cut crossover front, full back coverage. More fabric means more forgiveness. The Ruby's folded waistband and V-front construction accommodate a wider range of hip measurements per size. True to size is correct for most wearers; size up only if you prefer a looser, lower-riding waistband.
One-Piece Swimsuit Sizing
Le Club Original's one-piece swimsuits use a combined bust-and-hip measurement. Because one-pieces can't be sized independently top and bottom, they work best when your bust and hip measurements fall within the same size range.
| Le Club Size | US Size | Cup Size | Hips (at fullest point) | Natural Waist |
|---|---|---|---|---|
| S | 6 | B | 37–38" | 26–27" |
| M | 8 | B+/C | 39–40" | 28–29" |
| L | 10 | C+/D | 41–42" | 30–31" |
If your cup size and hip measurement are in different size categories — for example, a size S cup and a size M hip — a bikini separate will fit you significantly better than a one-piece. Le Club's bikini separates are designed precisely for this reason. See our mix and match guide for how to build the right combination.
Resortwear Sizing
Le Club Original resortwear (cover-ups, sarongs, and beach shirts) follows standard women's sizing.
| Le Club Size | US Size | Hips (at fullest point) | Natural Waist |
|---|---|---|---|
| S | 6 | 37–38" | 26–27" |
| M | 8 | 39–40" | 28–29" |
| L | 10 | 41–42" | 30–31" |
Sarongs and shade wraps are one-size. Cover-up shirts are cut with a relaxed fit and generally run true to size or slightly generous — if you prefer a more fitted look, size down.
Quick Reference: How to Pick Your Size in 3 Steps
- Measure your hips (at fullest point). This determines your bottom size.
- Know your cup size (S=B, M=B+/C, L=C+/D). This determines your top size. See the measurement instructions above if you need help calculating it.
- Check if they match. If yes, both pieces in the same size. If not, buy each piece in its own size — that's exactly what Le Club's separates model is designed for.

Frequently Asked Questions
What sizes does Le Club Original women's swimwear come in? Le Club Original women's bikini tops, bikini bottoms, and one-piece swimsuits are available in S (US 6), M (US 8), and L (US 10). Resortwear follows the same S–L range, with sarongs and wraps available in one size.
Do Le Club Original swimwear tops and bottoms run true to size? Generally yes, but fit depends on the style. Triangle tops (Willow, Liliana, Mila) are the most adjustable and forgiving. The bralette (Olivia) and underwire (Daisy) tops fit closer to true size. For bottoms, cheeky styles tend to run slightly small — if between sizes, size up. Full coverage hipster bottoms (Ruby) run true to size.
I'm a size S on top and a size M on the bottom. What should I do? Buy an S top and an M bottom. Le Club Original sells all bikini tops and bottoms as separates so you can size each piece to your own proportions. This is one of the key advantages of buying bikini separates over a fixed set.
How do I measure my hips correctly for a bikini bottom? Stand with feet together and wrap a soft tape measure around the fullest part of your hips and seat — typically 7–9 inches below your natural waist. Do not use your waist measurement; it will be too small. This hip measurement determines your Le Club bottom size.
How do I size a Le Club bikini top? Le Club tops are sized by cup size, not bust circumference: S fits a B cup, M fits B+/C, and L fits C+/D. If you know your bra size, use the cup letter directly. If you don't, measure your bust at the fullest point and subtract your underbust measurement — the difference in inches gives your cup size (2" = B, 3" = C, 4" = D).
Does Le Club swimwear stretch after wear? Le Club Original swimwear is made from 4-way stretch recycled fabric — recycled polyester-spandex in most tops, recycled nylon-spandex in bottoms. These fabrics retain their shape well with proper care. Avoid machine washing and wringing; rinse in cold water and lay flat to dry. Repeated chlorine or heavy machine washing will reduce fabric elasticity over time.
What if I'm between sizes at Le Club Original? For triangle tops and bandeau styles, size down — the adjustable ties compensate. For structured styles (bralette, underwire), size up. For cheeky bottoms, size up. For full coverage hipster bottoms, stay true to size. When in doubt, go with the size that accommodates your largest measurement.
Can I return or exchange if the size doesn't fit? Le Club Original accepts returns of full-price, unworn items within 14 days of receipt with original tags attached. See the full return policy for details.
