6 pack of racerback nursing tank tops. All 6 are Medium sized. One dark blue polkadot, one blue, one white, one dark green, and two black. As a mom of 4, I wish I would have found these on my first baby, not my fourth! These are the most comfortable tanks to wear postpartum as they flare out below the bra line. The bust is a double-layered cotton fabric with an elastic band. Extremely comfortable and easy to use.
