Button 2 Piece - LincolnGood things come in pairs and our tops + bottoms are no exception. Theyre made from our signature silky soft material for a stretchy, comfy fit with functional buttons and fold over waistband for room to grow (or to wear high waisted). Say goodbye to socks that slip right off with built in footies (on the newborn size only) to keep those tiny toes warm without the fuss. Unbelievably sweet mixing & matching approved. Sizes: Newborn 3 Month: 6 12 pounds
