This is a 4-piece set of matching tops and pants for sisters. Sizes are 100 and 110. I received this set as a gift, but my child often gets dirty, so I couldn't dress them in white clothes, and the tops didn't match the pants, so I only wore them a few times. There are some stains on the pants. Tops and pants can be purchased separately. I am also selling many other matching outfits for sisters.
