Bought it in Oatmeal...
Not impressed by the way the bottom has that unfinished quality to it. Would be a 5/5 hoodie if it didn't have that at the bottom. It's also thin material. I will still wear it, but living in Canada it's probably not going to get as much wear as it would if it were warmer.
That said, I went with a L. I'm 5'6.5", 132 lbs, and an A-cup. Probably should have gone with an M as it's loose.
I like the color and the size of the hood so I am keeping it. I really wish the bottom didn't have that fake fray going on though. :/ You can't really tell from the pictures, but be warned.
