Appearance and Sizing
Dress: When I got it out of the box, I realized the dress was a bit more reddish-pink than I was expecting. However, that ends up making it a lovely shade of bright red. It adds a Latin tint, which goes nicely with the overall look. I'm a size 6, and it fit perfectly without needing to stretch. It tightens nicely over your body, and it flatters nicely. The bottom flares out and is loose enough that it'll blow up with a little bit of effort. The only steps to get in are to step in and tie it off in the back.
Thong: The thong is a simple black see-through affair. It's hard to notice under the dress (or you can go without if you prefer). It's of decent quality, but you might want to replace it with a more expensive black one that you bought elsewhere.

Materials and Cleaning
It's made of a mix of nylon and spandex, so it's both sturdy and smooth. Thanks to the stretchiness of nylon and spandex, you don't have to worry about ruining it by stretching it to get in or out quickly. Out of the package, it came without any smell or odor. Even after some warm usage, it didn't pick up any oils, sweat, or smell. Cleaning it involves hand washing with warm water and a gentle soap. Be careful not to use hot water, since it would ruin the spandex. After washing, let it air dry and you're good to go.

Packaging
Nothing all that special, it comes packaged in a simple cardboard/plastic package with the same picture on the front as the product page. Since the dress is wrinkle resistant, you can easily fold it up and stash it in a drawer without needing the package. The package is mostly recyclable, so it's not a big loss to recycle it.
