This two-piece sweatsuit has quickly become one of my favorite lazy yet polished outfits. I am 5'5\" and 185 lbs, and ordered an XLarge. The fit was perfect overall. The pants fit comfortably, and the hoodie has that cozy, oversized feel without looking sloppy. If you like a more fitted hoodie, you might size down for the top, but I loved the relaxed look for travel. The fabric is super lightweight and breathable, so I never felt stuffy or overheated even in busy airports. Perfect for early morning travel or lounging around and still looking put together. Highly recommend.
