I ordered 4 of these shirts and made sure to get all 3 sizes. I was glad I did as the small was too small for my small 18-year-old daughter. I think it is 1 inch less wide than a typical unisex t-shirt (17" vs 18" wide on the small.) Did not measure the medium or the large, but I say size up as I do not think unisex sizing is accurate on this one. Two are gifts (one for me) but the small one will have to be donated to a child. Have not worn or washed so cannot speak to wear. Love the company--encouraging and kind. Highly recommend.
