Start at the bottom of your suitcase and place all clothes you will need for your last day there; pants, tops, socks, undies. Next layer, next to last day there… and so on, and so on.
You will end up with the top layer being the first pair of clothes you’ll need on your arrival.
I used to tend to over pack, so this helps to organize each day. I also try to rely on very few changes of shoes… and those go around the side. A small jewelry bag with multiple compartments and a small bag for toiletries and make-up.
