Senior pic clothing help?

I'm allowed 4 outfits (quick changes don't count). I have a pink sun dress that I want to wear, a flowy floral top and pink/red shorts, a cream lace dress, and then, something more country-oriented to do with my horses. I originally wanted to do a show shirt with my Arab and then maybe just plaid with my Mini, but I've run out on outfits, so probably just do nice plaid and sparkly belt with both. I also wanted to incorporate an outfit that shows off my hourglass figure (the dresses might a little) and something white because it's tradition, shows purity and femininity, etc. I'm over my limit! Any advice? How to maybe merge some of these, what to cut, things I haven't thought of altogether that'd be nice? Thanks!
