First off I'd like to say I love this shirt. It's soft and comfortable and fits very well.
That said, there were a few issues/drawbacks.
First off, the tag was sewn in with clear plastic thread which might irritate some people and made tag removal necessary for me. I hate doing this but I'm used to it.
Second, this item is listed as cotton, and the tag itself says 100% cotton, however this shirt is very stretchy and is definitely a cotton blend.
