This can be by item, by day, by outfit, etc. — whatever makes the most sense to you. "By sorting and packing this way, you will know exactly where things are and will be able to access anything as you need it," says Koplowitz.
"I personally like to group all like items and pack them individually. This includes: tank tops, underwear, pajamas, bottoms, dresses, jewelry, etc. I do this for my toiletries as well, which include: hair, skincare/daily routine, shower, meds, etc.," she says.
Another way to maintain categories is with a luggage organizer in your bag. The Stow-N-Go Portable Luggage System ($25-30) is a multitiered organizer that folds down into carry-on-size bags 20 inches and larger, saving up to 30 percent of space. Just hang it from its sturdy hooks, pack, and collapse into your bag. When you stop for the night, hang it from a closet or shower rod or even off a desk or table and unfold it for easy access to everything you need. It even features a zippered compartment for dirty laundry.
