The best way to fit more into your bag is to have a suitcase that grows with your packing needs. Expandable suitcases double as two bags in one, often starting out carry-on size but expanding to a larger bag when needed. We love the Briggs & Riley Baseline Domestic Carry-On Expandable Upright, which grows by 25 percent with the pull of a lever. If you're packing for a big trip (or need extra souvenir space on a return flight), simply expand the suitcase.
“I’m a firm believer that everything you need for a trip — whether it be three days or three weeks — should be able to be packed in a carry-on. This is simple once you master the art of layering your clothes. Choose a color combination for your attire and pack only pieces that match this so that you can mix, match and layer to create different looks (instead of packing completely separate outfits).”
