How to Measure Yourself
Use a soft measuring tape and stand naturally to take your measurements. It's best to measure over undergarments or close-fitting clothing.
- Bust: Measure around the fullest part of your bust while wearing a bra that fits well.
- Waist: Measure around your natural waistline — the narrowest part of your torso.
- Hips: Measure around the fullest part of your hips and bottom (roughly 20cm below your waist).
Between Sizes?
- If your measurements fall between two sizes, we suggest choosing the larger size for a more comfortable fit — especially for tailored or slim-cut pieces.
- For looser, relaxed styles, your usual size should be perfect.
Style + Fit Guidance
Every product page includes specific fit notes, like:
- “True to size” for standard cuts
- “Runs small – consider sizing up” for tighter fits
- “Oversized fit” for looser silhouettes
