My fiancé is an XL in polos. The polos I’ve bought in stores fit him perfectly however this polo - it’s almost laughable - the sizing. I even sized up on this because of other reviews. It is STILL way too small! It’s more like a very small medium. He did try this on just for me to take a picture for this review so you can see how freakin small this polo runs. I suppose it’d fit a thin and lanky man but my fiancé isn’t that. Regardless, this polo does not have accurate sizing. Which is too bad because the material is soft and felt nice.
