Trousers made of wrinkle-resistant fabric if possible, such as polyester blends or wool. These materials are less prone to creasing during travel. Lay the trousers flat on a clean surface with the front side facing up. Smooth out any wrinkles or folds with your hands. Be mindful not to overpack your trousers, as this can cause excessive wrinkling and make it difficult to find items in your suitcase. Stick to essential pairs and plan your outfits in advance to avoid unnecessary items. Upon reaching your destination, carefully unpack your trousers and hang them up or lay them flat to allow any creases to naturally fall out. If needed, you can use a handheld steamer or iron on low heat to remove any stubborn wrinkles.
