Part 1:
Got 'em! They're not turquoise, though - not yet. I went to The Bootery in Longwood, because a while ago someone said they would dye shoes there. They aren't doing dyes anymore, but they did have some dyeable shoes. I got a very simple pair - kind of like this, only there are no rhinestones on the toe strap, and the toe strap is about 1-1.5" wide. Now I just need to find someplace to dye them - any ideas?

Part 2:
Need to figure out shoes for DD, since she'll be the FG. She's wearing a turquoise dress, BMs are wearing black cocktail dresses. I feel like it'd look funny for her to wear ivory shoes with that, but then I feel like black shoes would be too dark for a little girl to wear at a spring wedding. A saleslady suggested dying shoes for her to match mine/match her dress, but that seems like overkill. Maybe metallic shoes? Whatcha think?
