Ultimate Train Water Resistant Jacket in Lily White

Sweaty Betty is a British activewear brand — UK is the primary size system and all charts lead with UK sizes. Unlike fashion brands, the sizing is granular: each trouser family has its own inseam options, and leggings come in four lengths. If you are 5'4" (163 cm) or under, consider Short length or 7/8th for full-length trousers and leggings. Apparel measurements are body measurements, not garment — if you fall between two sizes, size up as Sweaty Betty recommends. Sizes XL (UK 16–18) and XXL (UK 18–20) cover two UK sizes each, reflecting how the brand sells the ranges. Hips at XXL are published in half-inch precision (46.5 in / 118 cm), preserved as-is.
