Not only does this costume run true to size, contrary to all the negative reviews stating otherwise,, the quality is exactly what one should expect when it comes to halloween costumes, especially considering the lower price. It's good enough to get through a few costume parties, a night of Trick-or-Treating, and still be played with later. My five year old daughter loves the costume and looks just like Izzy when wearing it. It also washes well, as I've had to wash it at least two times since purchasing it. Obviously it's not the sort of thing that should ever go into the dryer, but it does dry quickly when laid out.As for the messy glittery top everyone is complaining about, I honestly have no idea what the big deal is. Yes, it is glittery but it didn't shed glitter all over the place as others have claimed. I had to vacuum up a little glitter, that's it, otherwise the glitter seems to be stuck to the costume pretty well. Like I said earlier: I've washed it at least two times and the glitter is still on the shirt.My only major complaint, which is not that big a deal, is Izzy's pixi-dust bag is sewn shut. Also it doesn't seem to lay flat when warn the correct way. Otherwise this costume is just fine for the cost.If you're looking for a high quality costume you need to be willing to pay more money. The Disney store tends to have higher quality costumes but the cost is quite a lot, unless you purchase their stuff on sale or clearance.
