These metallic shirts are glorious. I have a gold one and a purple one (the purple, it should be noted, looks a bit more pink than the Amazon photo had me believe), and both are fantastic. The inner lining is soft and feels high-quality, and the general look and feel of the shirt is far beyond what I'd expect for something that costs around $20 online.

I normally wear a size S t-shirt, and ordered this in a size S (the label says M) and the fit was about right, though maybe a half-size larger than a typical size S. I bought my second one in size XS (the label says S), and it felt true to a size S in the USA.
