These are newborn undershirts that I purchased and pre-washed but never used. The size is 50cm. There are 4 pieces in the set: the upper left one is a short undershirt, and the other 3 are long undershirts. They are in beautiful condition as they have never been worn. There may be some fading due to storage. Please understand that this is a personal inspection. Please purchase only if you understand that these items have been stored at home.
