After putting this tee on, I bought like five more in different colors because it magically made me look ten lbs smaller? I have not lost any extra weight. Haven't worked out in a month. It's something to do with the cut of this tee and where the arm hits! So incredibly flattering for my body. I'm in 2X here, which according to size chart, is my true size. Love these Old Navy shorts, too. They're true to size and running shorts that go up past your belly button despite saying mid rise. They are lined, but so comfortable! A perfect summer short. True to size
