Slim fit shirt, so we ordered on size up. This was for my son for a wedding. He usually wears a 1x, but since this was slim fit, we ordered a 2x and that was a perfect fit. It's not a super thin shirt (important since it's white), fit well, looked very good and was comfortable. My son got several compliments on his shirt. To me, it's a tad pricey, but it is a nice product overall.Picture included of he and I at the wedding. Nearly all of both of our outfits were bought on Best Buy.
