This is a set of three romper pajamas purchased from Belle Maison. The size is 70. I bought these about 5 years ago, and my two children used them for a total of two seasons. Each was worn about 20 times. They wore these alone indoors during the winter. Since they are from Belle Maison, I think the quality is quite good. They are generally well-used and have some pilling. The yellow one is particularly noticeable (see the last photo). These are used items, so they are not in perfect condition. Please understand this before purchasing.
