I wanted to have a hoodie with a slim fit to be part of an outfit and this one looked to be it in the quality I wanted. Most of the reviews said they ran large so I ordered a medium instead of my usual large. Even in medium (8/10) the arms are slim and plenty long (I am 5'7" usual size 10/12 jean, 12 top) and the side panels look nice, it is long in the waist so it comes down well over your hips. It will work well over a t-shirt, under my leather jacket on the bike, and long enough to keep my end covered. Get your regular size if you plan on wearing it with layers underneath and more as a top coat as the arms are also slim fitting like a Junior fit. The fabric is thinner than most men's heavy athletic hoodies but is quite warm, more of a sueded micro-fleece finish to the lining, The hood is large and works well on a chilly,windy day without plastering your hair to your head. I hate to say I have not washed it yet, planning on cold water and low dryer hoping arm length does not shrink. The Amazon size chart measurements are correct for hip, waist and chest. I will update if it shrinks.

Decided to update and let you all know it did NOT shrink washed in cold water and low heat dryer. It didn't fade either.
