UK Size Guide

Built for performance. Sized for your body. Use your body measurements in centimetres (or inches) to find your perfect FYM fit. If you're between sizes, size up. Compression styles are designed to fit close to the body — if you prefer a relaxed feel, go one size up.

How to Measure

• Chest/Bust: Wrap the tape around the fullest part of your chest, keeping it level and parallel to the floor.
• Waist: Measure around your natural waistline — the narrowest part of your torso.
• Hips/Seat: Stand with feet together and measure around the fullest part of your hips and seat.

Tip: Use a soft measuring tape and measure over underwear or light clothing for the most accurate result.

Fit Guide

• Compression fit — Designed to sit close to the body and support muscle during training. Size up if you prefer less restriction.
• Regular fit — True to size with room to move. Ideal for training and everyday wear.
• Oversized fit — Intentionally relaxed. Size down if you want a less baggy look.
