Plumule Cardigan Sizing
Plumule is meant to be worn with 5” / 12.5 cm of positive ease at the bust.
However, I recommend choosing the size with the cross shoulder measurement closest to your own measurement. Measure from shoulder bone to shoulder bone, not including the ball of your arm.
See size chart and schematic in photos.
Sample is size 2 with pockets. Worn with ~5” / 12.5 cm of positive ease at the bust, ~2” / 7.5 cm of positive ease at the bicep.
