I ordered this jacket in a small. I'm 5'8 with a 40" chest. It was too big, so I sent it back for an XS. This version fit great!, but came with a slight stain on it. I ordered a third one...this version of XS was a different version of the jacket. Like a newer or older edition...can't tell for sure. So the 3rd one had no stains but also didn't fit nicely! It was longer and looser than the other two. Felt more like the original small I ordered. After all this damn trouble, I just decided to keep the one with the slight stain on it. Jeeeeeez people get it together.Not bad. I got a lot of good comments.This is great and comfortable. Easy to layer if the chest has an extra inch of size. The styling is striking and people notice it. The usually don’t know the origin, if they do you have an inside joke thing. Consider getting measured for a suit and use the size chart. Mine fit as expected. I do wish it came with a long option in the sleeves. I do feel it should have a zipper, it could always be cut off if used as a costume.I feel like a real smuggler ??Love all the useful pockets!Main draw back was no zipper or buttons to close. Runs extraordinarily small... The company recommends ordering a size larger... I'm not even sure if that's enoughIt was greatJacket was too tight and too short and has no buttons.
