Romper set, 2 pieces Size: 70cm The navy one has a button at the back of the neck, and the gray one has a button on the side of the neck, making them easy to put on and take off. The gray one is a romper type, so it looks like separates when worn, but you don't have to worry about it coming undone ^^ Both have been used. The navy one has some light blue stains in places, which are shown in the photos.
