"Great with leggings, but not a fan of the ties on top"
This dress looks great with leggings. It's not really thick, so it's not like putting on a sweatshirt. It would be good to wear coming out of the gym It seems to fit like some North Face things I own. I wasn't a fan of the ties hanging on the top though - but that could be just me. It's super comfortable and isn't too boxy. The large fit me and I am about 145 pounds, 5'7.
