Packing travel clothes is surely a burden for anyone, but if you follow simple rules, everything becomes easier. Think about your destination and occasion. Whether it is a business or a pleasure trip and how the weather would be like. Pack extra warm clothes just to be sure, because temperatures might change.
Go for natural fibers, simple designs that won't clutter your luggage. To make sure clothes won't wrinkle that much, try to roll them instead of folding. This will save space too.
