I absolutely love this t-shirt and want to get it, but am torn over which size to get it in. I usually order smalls, which fit well but not very tight. I think this t-shirt would be really great with a snug fit. How much smaller is the x-small? I'm 5'5 and 105 pounds, anybody out there with similar dimensions? Which did you get? (I don't plan on putting it in the dryer, so no need to worry about shrinking).
