Runs Large
Size: X-Large, Color: Dreamy Coral
Seems to be an okay shirt. It’s a little boxy and Definitely not slim fit. I’m an xl tee shirt guy so that’s what ordered. The body fits more like a 2xl but it’s not bad enough to bother returning. Kind of hoping it shrinks after a couple washes

Bad stitching
Size: Large, Color: Bright White
The shoulder seam missing stitching. So there was an inch hole in the seam. I stitched it myself but really should have returned for a replacement. I bought two others in different colors and the stitching was fine. I do love the fit of these t-shirts.
