From the photo with the tight buttons I thought they were too small for me as I have an athletic build ie. broad shoulders and back. However, when the shirts arrived and I put them on, they were very baggy, more like a regular fit or even like a husky. There was enough room along the torso to jump off the plane and return home. The only good thing about the sizes is that they are perfect for my shoulders. I didn't see anywhere on the packaging that it was described as "fitted" or "regular cut". But I bought enough fitted shirts to know they weren't. To return.
