I got the grey in a size medium.  Im 55 135 lbs and 34D.  Im nursing my baby boy and this shirt is perfect for that.  Whether Im pulling it down or lifting it up.  And of course it is the perfect staple to have in your wardrobe. It goes with everything leggings, jeans, skirts, shorts. Layer a cardigan, kimono, or a jean jacket over it.  Voila! It washes great on the delicate cycle and line drying it.
