i’ve got proof of purchase in 2 different ways: -a physical receipt (email ones can easily be faked) -a serial number that can be authenticated in any store so please do not feel worried about authenticity status, its as real as they come. i bought this jacket in store in Regents Street London bought in 2021, worn loads but still perfect. it was dry cleaned and serviced in store about 2 years ago, and worn like 3 times since then. only reason im selling is because my gym programme worked a little too well and its too small for me now Its an excellent conditions, obviously some wear and tear which comes from daily use for 2 years straight. nothing I can do about that. only serious buyers please. nothing below 550
