OK, at the risk of subjecting myself to ridicule, here is our #1 travel packing tip: You know all that old underwear everybody has that is so ready to be thrown out but you could squeeze one more use out of it......turn it into disposable travelwear! I have a crate in my laundry room just for the old stuff and whenever we travel, we take our underwear from there. Use once and toss.....it certainly limits the amount of laundry you have to do and you have the added benefit of extra room in your suitcase for all those unexpected souveneirs. Occassionally a really conscientious maid will remove our castoffs from the trash and lay them back on our bed which can be somewhat embarrassing considering how dingey they are, so it's a good idea to stick them in a plastic bag and tie them up. Of course, if we ever get into the proverbial car accident, it won't look too flattering for us, but I'll worry about that when the time comes.
I also try to pack things that can be worn interchangeably with other items, so although I may not wear the same exact outfit twice, I might use the individual pieces 2 or 3 times each. I keep basic pieces very plain and use scarves or funky jewelry to give them different looks. At this stage of my life, I'm not trying to be a fashionplate or impress anyone. Clothing is definitely not a priority and as long as I'm neat, clean and appropriate for the occasion, I'll be happy.
