Any plan where you lose your hat

ok kids...here's the deal. i'm going to the disneyland mickey's trick-or-treat hallowe'en party at the end of the month, so i dont have a lot of time. i made a joke to a friend of mine and suggested that he dress up as Yzma. well now he's working on a costume and wants me to be his Kronk. so...we're going with the "secret lab" costume as seen here:


and a close up here:


now...some of the stuff will be easy to find (the goggles, the gloves...) what i'm having a problem finding is a size 3X or 4X extra long lab coat. i need it to go to my mid-calf i'm guessing. i can make the designs on the coat once i get it, it's just a matter of getting it before i leave. i'm also going to need to get a beanie and put an antenna on it. now i could get one of those propeller beanies and cover it if you think that might work. i'm so excited about this 'cos it all started as a joke and now it's actually going to come to fruition!

so...if any of you might have a suggestion of where i could find an extra long, 3x or 4x lab coat in white for not too much money in the san francisco bay area, i would be ever so grateful! it's brilliant brilliant BRILLIANT!!!! **insert maniacal laughter**
