^ I would def put flip flops in your bag to wear to walk from house to house if you have heels on. Round 1 & 2 -I would look at the booklet but they are showing tennis shoes. Those or rainbows should be fine. Day 3 They are also showing flip flops. I would go with skirt appropriate sandals or a wedge. This day is typically a little bit dressier. j
I think you are ok with jean shorts just not cut off ones for round 1. AZ is so hot and casual that you should dress for comfort but still look very put together. Black or white shorts are fine as long as your cheeks are not hanging out the bottom.
