Bally blue French rain jacket trench coat vintage

Silvery baby blue trench coat / rain jacket from France. 100% polyester. Vintage. So beautiful and in Excellent condition. Size M I would say but there’s not tag. Beautiful detailing, openings in the back and front of shoulders for mobility and breathing, cute buttons and POCKETS. Pretty warm for fall weather despite it being so thin. If it hangs in your closed it doesn’t really wrinkle haha I just forgot about it and it was all smushed in a pile of clothes
