HELP me pick outfits please

  1. I'm going to Orlando in a few weeks for my DH's company seminar. I need multiple business casual outfits for all the different sessions. I have two already and I need about four or five others. So far I have pair of khaki, gray and black trousers I just need some shirts to go along with them. Some accessoires like belts necklaces and other things to spice up the outfits would be great. Thanks for your help!
  2. What about throwing in a couple shift dresses that are easy to dress up or down with a switch of accessories? I always like to pack dresses when I travel versus seperates.
  3. A dress is useful because you might want to do something different at night.
