Sleepies are honestly the sweetest outfit that you have ever seen! They are made from cotton onesies and minky. If you havent ever felt minky you are in for a treat, it is the softest material on earth- indescribably soft. The 0-3 month size has fold over sleeves so they cant scratch their face. The little girl style tie at the bottom with a large satin ribbon. The unisex style tie at the bottom with a smaller grosgrain ribbon and the boy styles have elastic encased in the bottom.
