What about a cute short white dress(not an athletic dress)

white house black market has a few short ones. There are a bunch of neat wedding dress designers that have short dresses.

I am wearing a long dress from Saja but she makes some great short ones along with checking on Etsy(a lot of great designers sell through Etsy for wedding gowns and can alter to your length and then the price is less due to less material/work).

Lots of things to think of!
