Sirene Bikinis Size Guide
Choosing the perfect bikini top starts with knowing your measurements — and your personal preference.
โNeed help? Just send us your underbust measurement and usual cup size — and we’ll recommend your perfect Sirene fit. โจ
โ1. Measure Your Underbust (Band Size)
Wrap a measuring tape snugly around your ribcage, just under your bust.
๐ Round to the nearest whole number in centimeters (e.g. 70, 75, 80, 85).
This number is your band size.
โ3. Choose Based on Personal Fit
Your Sirene top is designed to adapt beautifully — so let your comfort guide you:
-
๐ซ Prefer a tighter and more lifted fit?
→ Choose the smaller size -
๐ฌ Prefer a softer, more relaxed feel?
→ Choose the larger size
โ2. Identify the Cup Size You Normally Wear
Check the cup size from your current bra — A, B, C, D, or DD/E.
If you’re between two cup sizes, pick the one you usually feel most comfortable in.
โ๐ Example:
If you wear a 75C and like a snug fit → go for size S
If you wear a 75C and like it more relaxed → try size M
