Size Guide and Fit
EU Size FIND YOUR PERFECT FIT We know that shopping online can be tricky, especially when size standards vary by country. We use US Standard Sizing for all our products. Please use the conversion charts below to find your equivalent size in UK, EU, and International standards.
Pro Tip: If you are between sizes, we generally recommend sizing up for a more comfortable fit, unless the item is described as "Oversized" or has significant stretch.
1. HOW TO MEASURE Grab a tape measure and follow these tips to get the most accurate numbers. Measure directly on your body or over thin underwear.
- Bust / Chest: Measure around the fullest part of your chest/bust, keeping the tape horizontal and under your arms.
- Waist: Measure around your natural waistline (the narrowest part of your torso), usually just above your belly button.
- Hips: Stand with your feet together and measure around the fullest part of your hips/seat.
- Inseam (for Pants/Jeans): Measure from the top of your inner thigh down to the bottom of your ankle.
