The dress is beautiful, I have it in purple, a very beautiful shade. My daughter normally wears a size 5 but I went for a size 6-7 just in case and she definitely has room to grow so I would say true to size. The material is tacky and may not look great on all body types but should fit most little girls. ETA: After the first wash (I washed it myself, in cold water) the color of the dress has stained the white collar so that it is no longer pure white but a very faint shade of purple. It doesn't really matter to me, but it's something to watch out for.
