I’m a strong believer in the “everything in its place” rule and this even applies to the way I pack. Travel bags like this cute one from Caban help protect not only the contents of the bag but also other items in your suitcase. Where else are you going to put your not-quite-dry swimsuit or dusty running shoes? These bags are handy for storing bras, underwear, socks, toiletries and delicate items like silk camisoles. They are made of easy-to-clean nylon and come in several different designs. Caban travel bag, $9.
