Size Guide

Every number on this page is the garment, measured flat as it lies — not a body measurement. It is the same sheet our atelier cuts to, which is why it is given to a quarter of an inch.

Chapter 01 is graded S to XXL. The pyjama sets go one further, to 3XL.

How to read a table

• Bust, waist and hip are measured straight across the piece as it lies. Double them for the way round.
• Outseam runs from the top edge of the waistband down to the bottom hem.
• Switch between inches and centimetres with the control below. It moves every table on the page at once.
• These are small, hand-finished runs, so a little variation from piece to piece is normal.

Finding your size

Chapter 01 is cut to sleep in, which means relaxed, and it runs true to size. If you are between two sizes, the surest way to decide is to lay out something you already love to sleep in, measure it flat across the bust and the waist, and compare it with the numbers below.

Every piece carries its own table on its product page too, under Size & Fit, so you can check it beside the photographs.
