Boomerangs from Australia, wine from France, wooden clogs from Holland, a poncho from Bolivia, or maple syrup from Canada - whatever your souvenir of choice from a memorable trip, you will want to have enough room to bring them home! Classic mistake upon packing? Not leaving extra room for souvenirs. So when planning what clothes to bring, always remember to leave space or weight allowance for those things that might take your fancy while strolling through a market, souk, or Duty-Free.
Sometimes, that still isn't enough room - consider packing a collapsible duffel bag in the suitcase in case of incredible souvenir finds that just cannot be left behind.
