Prairie Bow Jacquard Midi Dress
Sister Jane uses letter sizes XS, S, M, M+, L, L+ and XL with UK, EU, Italian, US and Japanese equivalents – an M is a UK 10 / EU 38 / US 6. The brand recently expanded its range, so some labels may still show the old sizing (old L = new M+ / UK 12, old XL = new L / UK 14); go by the UK number.
