1. Decide if you like black or navy and take one. Not both.
2. Khaki is great. It goes with everything.
3. Check out the online stores that sell travel clothing. You can get great looking stuff that packs small, doesn't wrinkle, dries fast.
4. If you aren't picky about your shampoo, conditioner, soap, or lotion, don't pack them. Hotel rooms always provide them.
5. Get a packing envelope and a packing cube (I like the ones made by Eagle Creek.) It's incredible how much stuff you can put in one and it makes finding things in your suitcase neat and easy.
6. Limit yourself to 3 pairs of shoes. Two is even better, if you can manage it.

For plane trips:
7. Get some 3 oz. plastic bottles with screw tops for your liquids. That's the most the airlines will let you take.
8. In your carry-on put: a change of clothing, including underwear, trip itinerary, all your medicines and toiletries, all liquids and gels should be in a 1 quart zip lock bag.

For travel in Europe:
9. Take a thin face cloth. Your hotel may not provide them.

10. Shop the "travel-size" bins at places like Walmart, Bed,Bath and Beyond, Target, and most pharmacies. One small toothpaste is good for about one week.
11. Get individual foil packs of insecticide, aspirin, nail polish remover, and towelettes.
12. Find some really tiny containers and fill them with things like eye makeup remover, cologne.
13. Don't stress over things you might be forgetting. They have stores almost everywhere.

And remember:
Your clothes are NEW to everyone you meet on vacation--except your own family and they don't care.
