Calico Bamboo Short Sleeve

This was part of my first order from Dixxon. Nice shirt. Very light airy material great for summer wear. Quality seems nice, except for some frayed threads off the front buttons of all places, which you can see one of in the attached photo. Since it was my first order, I compared Dixxon's stated sizing with another brand I wear in a size 2xl. The sizing was very similar, so I ordered the 2x from Dixxon. It's small, it's a bit more like an XL in the other brand. I'd need at least a 3x from Dixxon. In the attached photos, you can see even the top 2 buttons are a bit tight. The stretch even more if my shoulders were straight and not shrugged forward to take the photo. I'm not sure Dixxon understands big guy sizing, and just ups their measurements from standard sizes, with broad shoulders/chest with a tapering waist going down. That may be true for body builders, but if someone is ordering 2x, 3x, 4x or bigger, I can probably guess most of them have bigger guts/bellies then chest. Perhaps Dixxon should offer a regular/trim fit and a "Budda Belly" fit for sizes 2X and up, with a more relaxed fit in the waist/belly area. ....I want credit for the name. lol
