This is a set of rompers. Neither can be converted into a dress-all. I received both of them new from someone else and had my child wear them until around autumn. They are now too small for winter, so I am selling them. The brands for photos 2 through 7 are unknown, but they were made of a waffle-like fabric and were easy to put on. Photos 8 through 14 show "Nishimatsuya" marked on the tags. As shown in photos 10 and 14, there are faint stains on the right cuffs, and faint blackish marks from pilling on the back of the right leg, but neither is very noticeable. Both have been worn multiple times, so there is some sign of use. I had my child wear them as autumn clothing, but they are slightly thin, so I think they can also be used in early spring.
