Simple secrets to keeping business suits wrinkle free *
Hanger: Must be wood, with a rubber bar to hold pants in place without clips. Try the Container Store's Walnut Suit Hanger with Ribbed Bar, $10.
Tissue Paper: Crumple into arm-shaped tubes and slide into sleeves from the top. Kreinik Acid-Free Tissue Paper won't fall apart. $8.25 for 12 sheets at Kmart.
Garment Bag: No dry cleaner cellophane, please. Heavy-gauge plastic—like the PEVA Clear Suit Bag, $13 at the Container Store—protects clothes when bags are thrown around.

The best way to pack four days' worth of clothes: We tested three methods
How to: Fold pants and lay at the bottom of your case. Next, shirts (arms bent behind, body doubled over) and then jackets, front shoulders together, facing inward, with the arms wrapped around one side. Packing Time: 10:23 minutes. Wrinkle Factor: 4 out of 10. Pronounced, hard creases; few small wrinkles. Takeaway: Packs the most in, but the wrinkle factor makes this risky for quick trips.
How to: Roll dry-clean items (suits, shirts) loosely from the collar or waist down, then place in middle of the bag. T-shirts, sweaters, and jeans can be rolled tightly and placed on the sides like a firewood pile. Shoes, socks, and dopp kit go at bag's ends. Packing Time: 9:44 minutes. Wrinkle Factor: 3 out of 10. Erased by a quick shower steam. Takeaway: Easy, efficient, and with the fewest wrinkles: the all-around best.
How to: Wrap clothes around a "core object" (dopp kit and/or shoes). Begin by aligning pants to the top of your core and wrapping legs around the top. Follow in alternating directions with suit coats (collars lined up with the core), sweaters, shirts. Packing Time: 23:24 minutes. Wrinkle Factor: 6 out of 10. Small and easily steamed away. Takeaway: No hard creases, but takes time and suitcase space.
