[EX Q]: The sizing of this costume was fairly accurate but it very cheaply made. After only a few wears, the mask and belt both broke. I wouldn't recommend this costume.
[EX A]: Negative

[EX Q]: Bought this set based on low price and good reviews. Works fine for poking logs occasionally and cleaning up when stove is cold, but while using the shovel in the fire, the black coating started bubbling, then caught fire.
[EX A]: Negative

[EX Q]: This book is so typical of Southern Families with a strong matriarchal leader. I laughed out loud while reading because Ms Smith uses comical pharses I have grown up hearing. This is an awesome book.
[EX A]:
Positive
