After consultation with the boyfriend: If you're bigger, lots of good socks and underwear (socks are optional if you won't wear socks), a good pair of sandals or two, some shorts that fit properly. A few good books to tide you over until you get to a good bookstore. Some "home food" to be eaten on emergency days only.
That's about it, I think. Just a note for girls coming here: Bring MANY bras and panties, cuz the quality here sucks! (unless you're into baby blue lace padded bras in the middle of summer!). Also, good women's clothing is harder to find due to differing tastes. If sequins, velvet and colour-blindness don't bother you, by all means shop here. Also, if you're more than about a 10, you may have trouble finding stuff, so stock up at home.
