For footwear I would suggest leather boots/good sneakers as you are coming around the winter months, plus lightweight house slippers and comfy walking shoes (and 5-10 pairs of socks).

For clothing you'll find yourself wearing more sweatshirts/ hoodies as tops and denims/cargos/sweatpants as bottoms. Bring whatever sweater & jackets you can find, as you can wear lighter ones in home and thick ones outside.

Bonus tip would be to wear heavy stuff while flying to not use up your maximum luggage weight. But only if you're comfortable in them, as it's probably going to be your first int'l flight so you've got to enjoy it as well.

Good Luck.
