When I bought this dress, it fit my daughter perfectly (length, arm size, width). However, after washing it has become much shorter making it look more like a tunic than a dress. The arm width and size is still great but the length has decreased by 2-3 inches. If I had to buy again I would increase the size but at this point it may be too wide. The material is a nice thick t-shirt fabric and doesn't look very worn after 2-3 washes, just too short.

Well the only important thing is that the 3 year old LOVES it but I actually wanted to explain it in this review so I bought it at 6/7 first and thought that it is it will be small. but they fit normal, they are big for her but look a bit silly so I suggest buying the true size you want because it should be something like a loose t-shirt, basically just a big cotton long sleeve t shirt so i bought it again down a size and it fits much better and it will grow to a larger size, after all i paid 8
