Like the others:

1. Toiletries, shoes and towel at work. I bring a new towel in weekly. I keep a sport coat at work "just in case".

2. Clothes are rolled and put into a plastic bag that goes into a trunk bag. If you lay your clothes out with no wrinkles, and fold carefully to the desired width and then roll your outside garments (pants and shirt) carefully around your inside garments (undies, tee, socks), they will come out the other side remarkably wrinkle-free.
