Choose your hygiene items. Basics include: lotion, tampons/pads, wet wipes, Kleenex, and nail clippers. You may also want: travel sized deodorant, nail cleaner, tweezers, and makeup remover/toner.
Choose your wardrobe items. Basics include: safety pins, small scissors, and a small bottle of clear nail polish (to stop runs in socks and nylons- also great if you need to touch up your nails!).
