Im rushing at a competitive SEC school in three days!

Can't wait. I've already bought quite a few dresses with shoes and accessories but i can't really decide which ones to wear. I'd love to have the input of you ladies!
Here are links/pictures to some of them:

Mint:
Red with cutout:
I also have a dress that is similar in style to the ones above (high neck, sleeveless) that has red dots that are a lace overlay to an orange slip. If you understand what I'm describing. Keep in mind all of the dresses are a little bit longer on me (hit right above my knee) because I'm only about 5'3.
Also, for pref, is it better to stick with a classic style (belted, black, and high necked tulip shaped dress) or would one that has a v neck and a belt as well as a little bit of ruffle also appropriate? Any and all critique is appreciated! Thanks!
