Size Guide

We are excited to expand and introduce 0P to our women's size range. 0P is designed to cater for petite and shorter frames typically under 5’3” / 160cm tall to alleviate the trouble of alterations, specifically in length. Whilst the body measurements only reduce by approximately 2.5cm from size 0, the garment length reduces by an average of 10cm and arm length by 3cm.

Please see our full size guide below. For other fit advice, if your measurements are not consistent with a single column, use your waist measurement to determine your ideal size or reach out to our customer care team if there are any specific styles you are interested in to provide garment measurements and fit advice.

Measuring Guide

Bust

Place one end of the tape measure at the fullest part of your bust, wrap it around (under your armpits, around your shoulder blades, and back to the front) to get the measurement.

Underbust

Measure directly under your bust (around your rib cage, where your bra band sits), keeping the tape level to the floor.

Waist

Use the tape to circle your waist (like a belt) at your natural waistline, which is located above your belly button and below your rib cage.

Hips

Start at one hip and wrap the tape measure around your rear, around the other hip, and back to where you started. Make sure the tape is over the largest part of your buttocks.
