I was really worried that I didn't order the right size, especially for a costume like this that is supposed to be skin tight, but it fits perfect, I'm so excited to wear it! I was originally going to order the Medium, but after reading all the other reviews that said to order a size bigger, I'm glad I went with a large. I'm 5'5 and weight 147 lbs and the Large fits perfectly, it's not super tight and leaves me plenty of room to breathe. I think the neck piece fits fine if you're not super picky-it does feel kind of tight when you try to bend over but it's a one piece costume, what do you expect? The neck piece feels fine to me if you're not doing any crazy movements. I think I could have ordered the Medium and it would have fit, but that's if you want it to be super skin tight. The large fits nicely to my body and still leaves me room to move around. It definitely has a plastic/rubbery smell to it when you open it, but again, it's brand new, what do you expect? The material is nice and sleek and has a nice shine to it. You'll definitely want to wear some type of padding for your chest as the material shows every outline up there. Same for the underwear, wear something that doesn't show any lines or go commando, otherwise everyone will be able to see what type of underwear you're wearing. I think the belt does come 'One Size Fits All' because it's too big, just like all the other reviews said, but if you're crafty you can add some velcro and make it work. The headpiece is also a little weird, but the plastic is bendable so you can fix it however you want it to fit. The tail is a little awkward, it doesn't look all nice and curvy but that's because it comes all folded inside a box-I'm sure you can mess with it and make it look good since it has one of those bendable wires inside or just take it completely off. Overall, an awesome costume, it does show every curve and crevice of your body, so if you're self conscious about how you look, this might not be right for you. I'm not going to be super picky and take away a star just because of the weird tail and belt, because I wasn't expecting a 100% perfect costume. I rated it 5 stars because it fits so well to my body and is super sexy-the headpiece, belt and tail are just small details that you can either keep or replace if you're not satisfied with them. Just add some black knee high boots and gloves and you'll be set! Also, I ordered this on Monday and chose the 1-3 day shipping since Halloween is Thursday, and I got it by Wednesday, very fast service!
