I'll admit, I was one of the most skeptical people trying it out. I thought that there's no way an app would be able to properly measure me by simply twirling once. I went through the process because it was super quick and I liked how I could customize my shirt the way I liked it. Words cannot express my astonishment when I received the package in the mail. The shirt fit so nicely and the quality was incredible. I wore it that same night, and then again the next day. Def worth trying out, especially if you dislike shopping like I do.
