I got this as a present to myself after having my baby, and let me tell you, I’ve never owned a more comfortable and fashionable set! Just unmatched. I love how easy it is to wear postpartum. Im a pretty traditional medium, and the medium was totally perfect. 5’2, 140 lbs, I got medium in the top and bottom. I just adore it and can’t wait to get more Altair wear!
