[EX Q]: This is a fabulous costume! My daughter loves it and has had it on every day since it arrived last week. She even slept in it a couple of nights. The other reviews are correct in saying that it needs some mending. We had to reinforce the velcro on the mask and the elastic on the bottom of the boots. After a little stitching it is fine. We also sewed on a small piece of material to the back of the face mask so that it wouldn't stretch any further and tear. This was a fabulous idea. Do it! I only deducted one star for this because the rest of it is great. The material is a durable shiny pink. My daughter is a size 4 and wears a size 9 shoe and the small fits perfectly. If she were a 5 or older I would get the medium. Totally worth the money.
[EX A]: Positive

[EX Q]: I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.
[EX A]: Positive

[EX Q]: Even that single star is more than this book is worth. My Engligh professor assigned this book to me during my sophomore year of college (along with Nectar in a Sieve, a far better, though not terrific book), and what little I remember of it was that it was just awful (and offal). Her writing is repetitive and choppy, perhaps descriptive but disgustingly so. Do we really need to know the "wetness between [her] legs", or that she cooked her menstrual fluid into some poor soul's dinner? I couldn't stand the book. If you want quality, read something by Neil Gaiman, or Stephen King (his descriptions of a girl coming of age in Carrie are much better than this book). Drop the book, throw it, burn it, whatever. It's just not worth reading. How many trees did we lose to its production (and, more importantly, how many talented young writers were rejected because this woman was published). It's just a book not worth reading about a story not worth telling.
[EX A]:
Negative
