@costcoguide: New GAP crewnecks at Costco under $20! I am 5’8” so I always size up in anything long sleeve. I think they fit true to size. I tried on S,M & L in the video. If you want a more roomy cozy sweatshirt just size up one size. Otherwise you should be fine with your normal size. #costco #costcofinds #OOTD
