BR Peacoat Owners in or Around London (small or medium)

pleco

Does anybody in or around London have a small or medium BR peacoat that they would be willing to let me try on for a minute or two? I am prepared to come to you and reward you for your trouble. Sweating bullets over the sizing and I'd rather get it spot on. Help a brother out? Drop me a private message or post back here, please, I'd be majorly grateful to you!
