Buying a hoody on-line is challenging. You never know how heavy the fabric will be, or how it will fit. A lot of hoodys run big, but this one is true to size. If you like a trim fit, order the same size as your T shirts. If you like a bulky sweatshirt, order one size up. I would classify this as a medium weight sweatshirt. The fabric does have a "retro" look. It looks worn straight out of the box. That look is certainly popular these days, but if you do not like it, you may be disappointed in this shirt. You may also notice the outline of tooth ridge looks a little off. It appears to be a mirror image, so when you look at yourself in the mirror, tooth ridge is oriented correctly.
