Pack thinking about mix and matching

Do not pack something you can only wear twice during your stay. Make sure you take at least a whole week's worth of outfits and think of at least two ways of combining those to create a new one. You will have a whole three weeks of outfits that way. Try to make your combinations so they can be used once in winter and once in summer. Do not take super expensive clothing since you will be using it A LOT and it will deteriorate or get lost but make sure it's good quality to last a long time. Leave enough space to bring some stuff back too. Don't buy souvenirs that are too big but do bring memories from abroad with you. You will miss it when you are back. You can sell your clothes before coming home to make more souvenir money too.
