I used the sizing tool that suggests the correct size for Oxknit garments. It suggested I get 2XL for all of my garments. I bought 3 garments. One fit perfectly, the second fit slightly big and felt like it could be shrunk a little to get a nice fit. The third (this one) did not fit at all and was way too big, and was swimming on me. It is way too big, and it is unfeasible to return due to shipping and handling costs. Due to the inconsistency in sizing among garments and inability to return or exhange without having to purchase another size outright makes it difficult to recommend purchasing from Oxknit. They have very nice garments but purchase at your own peril.
