How to Find Your Perfect Swimsuit Size (Without the Guesswork)
Raise your hand if you've ever ordered a swimsuit online, waited excitedly for it to arrive, tried it on — and it just didn't fit. ✋
Too tight in the bust. Too loose in the waist. Rides up in the back. Gaps at the sides. Sound familiar?
You're not alone. Swimsuit sizing is notoriously tricky — and it's not your body that's the problem. It's the guesswork. Most people order based on their usual clothing size and hope for the best. But swimsuit sizing works differently, and once you understand how, finding the perfect fit becomes so much easier.
This guide will walk you through everything you need to know. Let's get it right the first time. 👙

📏 Step 1: Take Your Measurements (The Right Way)
Before you look at any size chart, you need three key measurements. Grab a soft measuring tape and follow these steps:
🔵 Bust — Measure around the fullest part of your chest, keeping the tape parallel to the floor. Don't pull it too tight — you want it snug but comfortable. Write this number down.
🟢 Waist — Measure around your natural waist — the narrowest part of your torso, usually about an inch above your belly button. Again, snug but not tight.
🟡 Hips — Measure around the fullest part of your hips and bottom, usually about 7–9 inches below your natural waist. This is the measurement most people forget — and it's crucial for bikini bottoms and one-pieces.
💡 Pro tip: Measure yourself in your underwear, not over clothing. And if possible, have someone else take the measurements for you — it's much more accurate than doing it alone.

📊 Step 2: Read the Size Chart (Not Your Clothing Tag)
Here's the most important thing to know: your swimsuit size is not the same as your clothing size.
A size Medium in jeans might be a Large in swimwear. A size 8 dress might need a size 10 swimsuit. This is completely normal — swimwear is designed to stretch and compress, so sizing runs differently across brands.
Always use the brand's specific size chart and match your measurements — not your clothing size — to find the right fit. At EMOSWIM, every product page includes a detailed size chart with bust, waist, and hip measurements for each size.
What to do when you're between sizes:
🔵 For one-pieces: size up. A slightly larger suit is far more comfortable than one that's too tight, and you can always adjust straps.
🟢 For bikini tops: go by your bust measurement.
🟡 For bikini bottoms: go by your hip measurement.
🔴 If your top and bottom measurements fall in different sizes, order separates — it's the easiest solution.

✅ Step 3: Check the Fit (Before You Hit the Beach)
Once your swimsuit arrives, try it on at home before wearing it to the pool or beach. Here's what a well-fitting swimsuit should feel like:
✅ Bust — Cups should lie flat against your chest with no gaping or spillage. If you have built-in cups, they should fully contain your bust without squishing.
✅ Straps — Should sit comfortably on your shoulders without digging in or sliding off. Adjust them if needed — that's what they're there for!
✅ Waist & torso — Should feel snug but not restrictive. You should be able to breathe, bend, and move freely.
✅ Bottom — Should cover your seat fully without riding up. The leg openings should lie flat against your skin without cutting in.
✅ Overall — Move around! Raise your arms, bend over, sit down. A great swimsuit moves with you, not against you.

❌ Common Fit Problems (And How to Fix Them)
🔴 Straps keep falling off — Tighten the straps or try a racerback style that stays in place.
🔴 Cups are gaping — The bust cup is too large. Size down in the top, or try a different cup style.
🔴 Bottom rides up — The leg opening is too small. Size up in the bottom.
🔴 Torso feels too long or short — Look for styles labeled "long torso" or "short torso" — they exist!
🔴 Waistband digs in — Size up overall, or look for styles with a wider, softer waistband.
