How to Pack a Suitcase

This is a retrospective now, but I've been through six airports, two trips, and two continents in the last week, so here's what I have to say about the art of luggage.
Clothing: I was told not to worry about being fashionable- that the Chinese were more practical minded about that kind of thing. Yeah right. I've never seen so many cute boutiques, or walking advertisements for them. But the general rules still apply- aim for easy care and maximum options. Jeans that can be dressed up or down. Tops that don't wrinkle and can go lots of places. A minimal number of versatile shoes, a good dressy coat, a couple of sweaters.
Also, take a little as possible. You can rearrange a few well chosen items in a surprising number of ways.
Blanket/ wrap: I don't go anywhere without a paero in the bottom of my bag. It's a scarf, skirt, blanket, towel, sheet, laundry bag, privacy screen, table cloth or wall decoration depending on the need.
Makeup: on a long trip, I find that there is a real psychological benefit to having whatever you need to feel pretty every now and then.
Other basics: Journal- I don't keep one at home, but it's such a great way to remember things.
Something to munch, because airport food is always expensive.
All your paperwork, and a spare copy in every bag, just in case.
Your money, also spread between at least two locations.

some strong cord


Your carry on should have everything you really need to survive- a change of clothes, papers, money, and any valuables, since it's the least likely to be lost or raided. A plastic bag or two is also handy, to quarantine dirty clothes as they are worn, and maybe a big one to cover the bag with if you are going to spend time outdoors.

The art in a nutshell: Pack everything you need. Look for versatility. Pack no more than you need. Travel light, be happy.
