I usually wear small, went by reviews and ordered Medium. It fit well. I am 5'6"; 118 lbs. Slender build. Thank you Sebby!
I love the single breasted Sebby raincoat. The detachable hood is lined with a soft fabric as well. The code is a Great weight and looks very slimming on. I found it to run slightly small and move the buttons over a little to make it more comfortable purse.
