The sizing on this shirt is extremely generous. I've been wearing an XL in most of Chadwick's clothes, but I was swimming in that size in this shirt. Went down to a large, which is still too big but acceptable. I'm a little worried about laundering because do the sweet embroidery, but am going to try so maybe it will shrink a bit like all the rest do Chadwick's clothes. This would rate a 5 because it's so cute & well made, but the sizing is an issue.
