Help! Fabric suggestions, please

So we're going to a couple weddings this year — both of them in the midwest and both in my husband's family. Our daughter is going to be a flowergirl in both (though I have my doubts she will actually walk down any aisle, no matter how many lollipops and jellybeans she is promised. But that is for another day. This is about dresses).

I was thinking of what I could make for a spring wedding in Wisconsin. Wedding #1 is not far off — April 2. Wedding #2 isn't until the fall. Anyway, I think I have the design nailed down, but I need some help choosing fabrics. If you have any suggestions (with links!), please comment. No one ever comments here, though I can see how many pageviews I get. I know someone is reading this somewhere.

Anyway, I'm thinking the bodice of this dress (the Coffee Date Dress from Burdastyle.com):

 

On top of the fuller skirt below here (the Linda Skirt — also from Burdastyle.com)

I want to make the bodice in a bright print, maybe with a little retro appeal, and the skirt in a solid neutral, and then finish it with a nice wide sash in a colour that contrasts the print. Oh, and maybe a few layers of tulle (the same colour as the sash) peeking out underneath the skirt for fullness.

I already wasted 40 minutes of my daughter's precious naptime searching online fabric stores, and still can't decide. I thought I'd try outsourcing this. Suggestions?
