This goes for all countries. Plastic bags may be the devil's work, but they can also be a Godsend. Pack all your clothes in plastic bags before putting inside your backpack. Use them as "drawers" to separate things out. It makes life so much easier being able to lay your hands on the right thing and the right time. And when it comes to packing, you just shove all the plastic bags back into the backpack, and voila. They keep your items dry too. Take spare bags for shopping so you don't have to ask for one, only to throw it away five minutes later. Plastic bags. They are your friends.
