craftgrrl | I tired the faq with no luck.

I was wanting to make a costume for Halloween. I have it narrowed down to three choices with Jessica Rabbit being the one I like the most. I have a good idea of how to cut and piece the fabric like I need it but am running into one problem. I am busty and will need support in the dress.

Without adding straps and wearing a bra, how could I add support to the bust of the dress? For those of you who don't know what the dress looks like, there is a picture below the cut.

I'm pretty inexperienced with making my own costumes so I figured if I started in the next few months, I would have plenty of time to get it finished.

Also, does anyone know of a place where I could get that fabric (a red sparkly type) without waiting for the Halloween stuff to come out?
