I saw a review saying the person was about 170 size range and a medium fit them. I was a bit skeptical to order a medium as they style looked slim fitting. I am about 155 and thick in the middle. About a 34 waist. It fits great and actually makes me feel thinner than I am. I love the turquiose color, bright but not too much. I would definitely order in my colors. Hood is a nice size and I occassionally will put it on during a chilly night sitting outside. The fabric is a very good quality for the price point.I bought the tie-dye one in a small and it was way too big on me (I am 5'2 and 110 pounds). The sleeves looked comical completely covering my hands and it was really long and billowy on me. I tried to return it for an x-small but the did not carry that so I got a full refund and was able to keep the hoodie. So for a free hoodie I really can't complain! The colors are amazing and it seemed to have shrunk a little after drying it on high temperature in the dyer. It's a nice thing to just wear around the house.These run really small. I ordered a large. (I wear a size 10-12). When it arrived, it was so small that I gave it to my 10 year old daughter. It is only slighty loose on her. The fabric is thin, but I like that. It holds up well in the wash and seems to be well made otherwise.True to size.... I ordered a LG. I should have ordered a small.. I don't understand people's reviews saying it runs small.. run larger..The hoodie on this was so small I couldn't get it over my head, it was very short waisted, not at all over the hips like the model in the picture, and the sleeves were short as well, with the wrist opening double the size needed to just touch the skin. On top of all the ill-fitting complaints it left teal-colored balls of shedded material all over any shirt or dress I wore under it, and coated all the other clothing in the same washing load with the same teal colored lint messThin Comfy hoodie, I love the colors, but I did find it runs a bit large, I'm 5'3 and 170 lbs, I ordered a L but probably should have went with a MLove it, but bled onto other clothes with the first wash. I should of washed it separately. And it left a lot of lint on my other clothes, but over all...love the sweatshirt!This hoodie took FOREVER to get to me and I contacted the seller twice with zero response ever. I received it two weeks later than I wanted and then it didn't even fit! Ridiculous. The only thing I liked about the entire experience was the material.
