When I first unpacked this shirt, the first thing I noticed was how thin the fabric is. The pattern of the shirt itself, including where the seams are placed, is different. I was unsure, but after wearing it for the first time, I like the fit. Yes, it's see-through, but it's lightweight and moves well with my body. It's baggy in all the right places for free-flow movement. I ordered the XL and am happy with the sizing, as I am typically a US 16-18 in size.
