you can't you half to make it
to be honest try cosplay.com you can request to have it made it's expensive and takes a long time though, if you can't make one
That depends on WHICH costume you're looking for - I wouldn't recommend the most revealing one, though.
You can find a Minnie Mouse costume at your local Party City or Dallas Costume Shop. If you don't have any luck you can always try ebay.com.
ebay
If you want a cheap, used Minnie Mouse costume, I would suggest Ebay. Amazon.com and a local costume store are not bad ideas to check out as well. Good luck!
A decent adult Elvis costume can be found at Wholesale Halloween Costumes, Oriental Trading Company, Birthday in a Box, Costumes Super Center, Costume Craze, and Amazon.
