The quality of the Maggie top is fantastic. It's definitely not a piece that is going to fall apart after a year of use, if you take good care of it. I am a size 18, and ordered XXL. I definitely could have gone down a size. The built-in bra is not supportive enough to allow me to go without a bra (D cup), but that was never my expectation, anyway. The first time I wore it, I did an indoor century ride. I appreciate when workout clothing fits so well that you don't have think about it or adjust it every two minutes--the Maggie top fits the bill!
