I just adore this lightweight hooded raincoat and it's so well made too. Fully lined with elasticated cuffs, elasticated drawstring waist, deep front pockets with decorative zips, front covered zip with stud poppers, and a lined hood (also with elasticated drawstring).
Sizes S (UK10-12) Chest = 42”
M (UK12-14) Chest = 44”
L (UK14-16) Chest = 46”
XL (UK16-18) Chest = 48”
Length roughly 31”
I am a UK10 and the 10 is a good fit on me
I’d say they are true to size, in fact quite generous. I’m wearing a thick mohair sweater and a long sleeve tee underneath in these photos. It looks great with a thinner top underneath and with the waist drawn in
