Ralph Lauren. Since it's 12M, it's probably around one year old. It's sailor-style, refreshing, and very cute. There are three buttons in the back, and I think it will be cool enough with underwear or a romper underneath. There is a slight yellowing on the collar; it might come out more with stain removal. Please judge from the images. For those who understand that this is a used item, I do not have any pets, and I do not smoke.
