I am 5'6, 150 lbs., 36DD, and this hoodie in a Medium fits very nicely - it's not loose fitting, making you lose your shape (as a lot of guy-sized hoodies do). Instead, this is designed for with a woman's shape in mind - it hugs my curves and is long enough that I'm not constantly tugging it down with every move. I bought it along with the matching sweatpants, and wear this on Sundays to run errands, etc. A great set!
