I am 5'5, 140 pounds and went with a size medium to get a loose fit. The shirt is exactly, EXACTLY what I hoped it would be. When I buy new tees I am so often disappointed by the cheap feel and quality. This shirt feels heavier, and better quality - I think it will last a long time. The vintage style graphic comes with the perfect muted color palette. It is aged and worn in looking, making it look like the most epic thrift store find. The V shape of the graphic is really striking on, and I love the large shape of it - it takes up my whole torso. The tee itself runs kind of long in my opinion, I've worn it with a french tuck or fully tucked and it looked great. I also wear it to sleep in with pajama pants. I want to wear it all the time. I hope Wondery makes more like this because I'd absolutely buy them all.
