This is a striking vintage Salvatore Ferragamo tropical print ‘windbreaker’ style jacket, made from 100% polyester. Judging from the label, I estimate this item was made in the 1990s.
It is unlined, very lightweight, and I don’t believe it is waterproof.
The label states it is ‘one size’ and it has been shot on a UK10 mannequin. I believe it would fit a person up to a size UK14.
