Shoes and Bags
Bringat least 5 pairs.
-2 pairs of cute walking shoes
-1 Cute pair of dressy shoes for things like zone conference, church, and baptisms
-Slip on sandals or something for when you're at your house etc.
This kind of set-up would be good to last you awhile if you get like 2 quality walking shoes. Nicer quality shoes will save your back.
I would not take a large bag. Some people think they want a large bag that will like carry their PMG and QUAD but no. You don't want to carry something large and heavy. I just used a small iPad sized bag. The strap was leather so it lasted a while and it fit my iPad, BoM, and some pass along cards and it was all I really needed. Especially if you're serving in an iPad mission you really only need to carry that around.
