Michelle, you could have avoided the stress of the costume shop and borrowed one of mine.  I have 3 adorable costumes, only 1 of which I will be wearing this year.  I will be Robin minus the Batman - and yes, it covers my ass (barely).  That leaves Mini Mouse and Dorothy (including Toto in the basket) for you!  Both very cute and sexy, but not sleazy - in fact, they are girls' size 14, so more cute than sexy!
