I was not happy when I opened the package and saw the blue shirt instead of the pink one which I had ordered.  It also smells weird, but this is my first rashguard so I don't know if they are supposed to smell like that, I would think not though. I washed it and the smell was gone, might have been the wrapping or something.
I would have returned it but I really didn't want to deal with that over a wrong color, so I'll keep it, I haven't used it yet so hopefully it will work for me and if it does then I'll order the pink.
