Love the fit
Color: All White, Size: Small
I always feel like shirts are a little too baggy but this one does for incredibly nice. The material is really light feeling too. Definitely will buy more of these shirts
Edit: I’ve bought multiple of these shirts and they’re absolutely amazing. They’re also comfy and really good for the summer. There was a review that mentioned to avoid this shirt because they iron it. This shirt is nylon and spandex. I don’t understand why you would expose it to high heat like that especially knowing high heat can damage certain type of material. If you need to iron it, make sure your iron can adjust to those two fabric settings or take it to a place that professionally can do that.

Good shirt, but not perfect
I have bought three of these shirts. They fit well, look good, good value for the price, don't wrinkle easily. The fabric is VERY heavy and does not breathe well, so they are better suited for winter than summer wear. The placket tends to bunch up when you're seated, so wearing an undershirt can be helpful.
The only thing I'd change about it is the fastener on top would be better as a standard button, or be fastened closer to the shirt. When worn buttoned-up, there's enough room between the two halves of the shirt that one side folds down and there's an unnecessary collar gap that doesn't look great. When worn unbuttoned, the fastener dangles (which again, doesn't look great). The shirt also doesn't have collar stays, so the collar can roll up.

Heavy shirt
Color: All White, Size: Small
Looks good but is heavy, not like a traditional long sleeve shirt, I always use long sleeve shirts every day, but this one is heavy comparing with the other ones that I have
