There are a few ways you can pack efficiently for your next trip. Start by putting your shoes on the bottom of your suitcase. Shoe bags help protect your shoes from the stress of travel. Place jeans on top of the shoes, followed by underwear and socks. Buy several pairs of identical socks; this way, if a single sock gets lost, you'll have another to match. Next, pack sweaters of different weights in large, resealable bags. Shirts and pants go in last; place them inside garment bags (your dry cleaner should be able to supply you with extra bags) and fold them on top of the suitcase. Don't forget to include a sewing repair kit, books, and perhaps a portable stereo, an electronic game, or other entertaining items.
