UNIQLO Combination Underwear 5-Piece Set - Bundle - Colors: Light blue, light green, gray, rabbit pattern, sheep pattern - Design: Front opening, button closure - Quantity: Set of 5 Used during the newborn period to around 3 months. I rotated through about 10 pieces, so each piece was worn infrequently. My baby didn't spit up much, so there are no noticeable stains. Thank you for looking.
