Ironed clothes can be easily ruined when placed in a backpack, but there are a few simple things that can be done to keep them looking good. By following these tips, you can make sure your ironed clothes stay wrinkle-free and looking their best.   1. Always place your ironed clothes in a garment bag before putting them in your backpack. This will protect them from being crushed by other items in the bag.   2. If possible, pack your backpack so that the ironed clothes are at the top. This will prevent them from being wrinkled by heavier items in the bottom of the bag.   3. Put a dryer sheet in between each layer of clothing in your backpack. This will help to absorb any moisture and prevent wrinkles.   4. Finally, try to avoid packing too many items in your backpack. The more crowded it is, the more likely your ironed clothes are to become wrinkled.
