9M Size 75 Sleeve Length: Long Sleeve Design: Plain This is a Ralph Lauren denim dress. It's a thin shirt dress with long sleeves, but you can roll up the sleeves and secure them with buttons! The ruffles under the collar are cute. I didn't notice it when I was wearing it, but there are three small, brownish stains in the last photo. I didn't notice them at all when I was wearing it, but please refrain from purchasing if you are sensitive to such things. I mostly used it for going out, so I haven't worn it much. This is a used item, so please understand.
