So you started off a your trip with a perfectly organized suitcase - tops here, bottoms there, undies somewhere else. But so what? After a few days, your neat sections have become fabric amoebas, and you're just glad nothing you packed wrinkles that much. Here's something better: Shelves-To-Go packable shelves ($35-37). Arrange your things the way you would in your dresser at home, collapse the fabric sides when you're done, and you'll have your own mini-wardrobe to hang in the closet wherever you're staying.
