I received my Leia costume a few days ago. Here's my overall impression:
-Material: The material is a decent thickness, although I'd still recommend wearing something white underneath. The boot covers are a spongy material and look pretty ridiculous, but thankfully not too visible when wearing the whole ensemble. The belt is a limp, thin, piece of plastic.

-Size: As far as sizing goes, I'm 5'6" and 120 lbs, and the length is just fine, not too long or too short. As far as width goes, it is a bit roomy. The belt, which has velcro to secure it in place, was way too large even when tightened all the way, so I plan on modifying that by cutting it down to size and adding more velcro.

-Wig: I didn't even try on the wig because I plan on using my own hair to do Leia buns, but I'm not too impressed with the wig.

-Overall Quality: Costumes aren't generally expected to be high quality garments, and this was was fine for what it is: a cheaply made costume. Not worth the high price. I wouldn't recommend buying this unless you really have your heart set on being Princess Leia for Halloween and  are not deterred by the fact that you will be overpaying for a mediocre costume.
