The simplest option when it comes to folding pants for traveling is to make only vertical, lengthwise folds. This strategy is best for pants with "pleats" - vertical folds sewn into the fabric along the waist of the pants. If your pants have pleats, fold vertically along these. This way, even if the fold sets into the pants as a wrinkle, the long, continuous vertical wrinkles will look like the result of ironing. You may also fold the pants in half vertically to further save space. One of the big disadvantages of folding pants only vertically is that many suitcases simply aren't big enough to stretch the entire pant leg out in. If you're pressed for space, try rolling your pants. Fold the pants in half vertically and lay them on a clean, flat surface. Starting at the bottom, roll the pant legs into a tight bundle. This prevents wrinkles by exposing a minimum of the pants' surface area to other items in the suitcase and makes the pants take up relatively little space. If you can, you'll want to avoid folding dress pants horizontally, as this can contribute to creases that can't be explained away as the result of ironing. However, if you do fold your pants horizontally (this is usually done after folding the pants once vertically), you can minimize wrinkles by following the same rules as listed above for suit jackets - place only flat, folded items on top of them, place them in a bag if possible, and so on. One great idea for pants folded horizontally is to "sandwich" them within the two sides of the folded suit jacket. This provides them the protection of the inside-out jacket fabric as well as the jacket's bag.
