I planned on using this shirt strictly as a top layer, but its very stylish and well fitting so I now wear it casually for whatever occasion. It fits true to size if you compare it to the example images, very rapper-esque in that its supposed to be a baggy version of the sweatshirt, it really depends on your personal preference but if you do not like the baggy style, size down one. I am 5'9" 140lbs and the size small fits me exactly like it does the model in the photo. Black does come with a funky smell, but other than that, it is very warm and high quality.
