Pack only versatile pieces of clothing.

It might be tempting to want to pack your favorite standout pieces from your closet, but if you're looking to pack lighter, Banas recommends bringing pieces of clothing that go with everything and that you can layer.

"I always bring as many versatile items as I can," Banas said. "So a lot of layers, a lot of little cardigan sweaters, and T-shirts and things that you can layer over top of one another, and scarfs."

"Scarfs are great because they can double as a blanket on the airplane if it's a big enough scarf; it can be a sarong, a beach blanket, it can also just add a pop of color to your wardrobe."
