Great tux jacket, short shawl lapel is nice and easily worn casually. Nice hefty weight, can work as outerwear (I've done this). Fits generously on a true medium, this is not a super slim piece as some of you may remember from the last +J collection. A slim large might even be able to swing this. Could be tailored to fit a medium very nicely or worn a bit slouchy or with layers as I often did. Bottom button is a bit loose, super easy fix, any dry cleaner will do this for free.
