This is a Ralph Lauren dress. The size is 5, which I believe is around 5 years old in Japan. The red color with the gold pony is very cute, and it was a favorite. I still wanted to wear it, but it's too small, so I'm selling it. It's been worn a lot, so there is some wear and tear, and there are stains on the elbows. Please understand that this is a used item before purchasing.
