Women's Swimwear Size Guide
Finding the right swimsuit size is the first step toward feeling comfortable and confident at the beach or by the pool. At Tilatilata, our collections are designed with flattering fits and premium stretch fabrics that adapt naturally to your body.
Use the size charts below to determine the best size for bikini tops, bikini bottoms, one-piece swimsuits, two-piece sets, and beach cover-ups. If your measurements fall between two sizes, we generally recommend choosing the larger size for a more comfortable fit.
How to Measure Yourself
For the most accurate fit, measure yourself while wearing lightweight clothing or undergarments.
- Bust: Measure around the fullest part of your bust while keeping the measuring tape level.
- Waist: Measure around your natural waistline, usually the narrowest part of your torso.
- Hips: Measure around the fullest part of your hips while standing naturally.
- Torso (One-Piece Swimsuits): Start at the shoulder, measure down through the bust, between the legs, and back to the shoulder.
