Listed as size 2y, but it seems like it could fit from around 1 to 3 years old. This is an Oaxaca dress. I purchased it at Kodomo Beam. I've worn it about 3 times, but There is one loose thread on the left side. There is one stain. These are signs of wear that I noticed when listing the item, so I don't think they will affect wear, but please understand this before purchasing. Sleeve Length: Short Sleeve
