Hmmm, little Johnson County girl heading off to the MHK.
Wildcatt, where did you go to HS? I graduated from Olathe East back in 2001.
Anyways, follow the advice of these ladies here. Go simple and classy and you can't go wrong. Also you need to remember that you are going to Manhatten which is a lot more conservative in style than JOCO, and there are a lot of farm girls out there who are in the sororities and they are even more conservative about that type of stuff. Also a lot of houses will have alumni members around with varying degrees of power, and since they are most likely alumni from the surrounding areas, they are going to be even more conservative. Best not to do anything to offend anyone.
There will be plenty of time to show off your amazing sense of style, so save the pleated mini until then.
