It depends on where you are going, but I'm presuming the temperature will range from cool to chilly, so based on that, here are some ideas:
- 3 pair of jeans (one chic, dark wash pair, one more casual pair, and one pair you're not afraid of getting dirty/durable)
- 3 tank tops (good for anything)
- 3 shirts (simple, everyday wear)
- 1 pair khakis/dressier pants
- 1 pair sweats
- 1 long sleeve shirt/polo
- 1 hoody
- 1 jacket
- 1 set of PJ's
- 2 pairs of shoes (one pair of durable sneakers, one pair of nicer shoes, and, if you have the room, a pair of flip flops)
- Enough underwear/socks/bras
- Hair ties
- Toiletries
Always bring a pack of pads/tampons, you never know.
Alter this list to your personal needs.
