I bought a 'take care of yourself' and 'handle with care' hoodies. They came quickly but I bought mediums expecting them to fit like larges. Im 5'7", 160 lbs (usually wear mediums for a fitted look and larges for comfortable look), and they fit rather snug, so I'd say they're true to size despite the sizing info on the site.
It wasn't a big deal though, the company was very accommodating and the return and exchange process went very smoothly and quickly. I got XLs the second time and they fit exactly how I wanted (oversized) and are super comfortable and great material. I'm planning to buy some more in a couple months.
