Size Guide

Use the measurements and conversion tables below to find your perfect Goupick fit. Sizes shown are UK sizing unless stated otherwise, with US, EU and AUS equivalents included for reference.

How to Measure

For the most accurate fit, measure yourself directly over your underwear using a soft tape measure, and compare your measurements to the tables below rather than relying on the size you usually buy elsewhere.

  • Bust – measure around the fullest part of your bust, keeping the tape level and comfortably loose, not tight.
  • Waist – measure around the narrowest part of your natural waistline, usually just above your belly button.
  • Hips – measure around the fullest part of your hips and bottom, roughly 20cm (8in) below your waist.

Tip: ask someone to help you measure for the most accurate result, and keep the tape measure snug but not pulled tight.

Finding Your Fit

  • If your measurements fall between two sizes, we generally recommend sizing up for a more comfortable, relaxed fit – check the individual product description for the specific fabric, as stretch fabrics have more give than woven, non-stretch styles.
  • Product pages include garment-specific fit notes (e.g. "true to size", "fits small", "relaxed fit") – always check these alongside the size chart.
  • Still unsure? Our team is happy to help you pick the right size before you order.
