Worn once and in perfect condition! No defects whatsoever. So, essentially it is NWOT. This piece initially retailed for 430+ USD.
Given to me from the new 3.1 Phillip Lim boutique in Los Angeles by Phillip himself!

Details:
-Despite this being a men's piece, it is about as unisex as any piece you can imagine--as long as you wear a S or M (up to 46EU, I believe) it'll fit you like a glove.
-3.1 Phillip Lim distressed denim jacket in a light washed blue reconstructed denim motif. As seen in the Spring/Summer 2017 men’s RTW collection. This difficult to find piece features two front flap pockets, one with a unique ivory toned embroidered/knit trim, matching white button closures and a minimalist point collar.

Note: the tag does say XS, it's a large XS (that's how his sizes run); I would definitely say that this is akin to a S/M with a tailored, yet relaxed, fit.
