Super cute shirt! It is not the size it says it is, it runs very small. I'd say a 4-5 girls. My daughter is 6 and is the size of a 4 year old and it fits good though. I needed it to fit small but description is misleading.I thought it was a sweat shirt, it isn't and I was very disappointed when she opened it.Not a typical underarmour quality and sizingI had to return this.Under Amour makes great products. Not sure if this was a knock off. Really small - definitely not true to size. I returned it.It fit appropriately for size, good hoodie, granddaughter loved it.Washes up nicely, sizing is accurate, my granddaughter loves it.Quality was poor sizing was way off. Shirt looked ill fitting.
