This is a set of matching dresses for sisters in sizes 110 and 120. My mother gave them to us, but the children didn't like them. The size 120 was worn once, but the size 110 has never been worn. The size 120 dress has a stain on the chest that was there originally. I tried to remove it, but it wouldn't come off, and rubbing it caused some color fading. There are also a few other small stains. The third picture is a comparison of the two sizes. There isn't much difference, so I think they could be worn by twins.
