Here is the packing information you requested. To travel lightly with only a carryon bag and a personal bag one has to accept three things.
First, laundry will have to be done along the way. We do all ours by hand. It only takes 20 or so minutes a day. If you don’t have experience doing hand wash while traveling I can give you in a few tips. Or did I sent that already?
Second, you will wear the same outfit more than once -- perhaps even two or three times apiece.
Third, don't worry what others may think if they see you in the same outfit several times. You'll see them in the same outfits multiple times also. In addition, they don't pay your bills so why worry about what they think at all.
Don't take a hair dryer. Every place we’ve stayed in years has had one in the room, or we borrowed one from the front desk. Worst case scenario you can buy an el cheapo there and call it a souvenir.
General thoughts: Take only black, white, and grey clothing that can be mixed and matched. You can add a splash of color with a scarf or tee or tank. Take things that are light weight, wrinkle free, and will dry quickly. Several sources are Magellan's, Travel Smith, and Chico's. All have web sites and Chico's has regular stores. Chico's is really great.
If you take a lot of meds, get an extra label from the druggist, put it on a freezer zip lock, and put the pills in the baggie. Saves a ton of space and weight. Just take the data sheet with you to show what it is and that it is for you.
Take very little jewelry. One or two necklaces and ear pieces at the most.
Take only two purses at the most. Your regular day bag will do ok for daytime. If you feel the need for another then a small clutch for evening.
Don't take a lap top or tablet. It'll just take up space and add weight. Check email with a smart phone at a hot spot.
Three under shirts – two regular and one tank top – wear one and pack two.
Five underwear -- wear one and pack four.
Three bras -- wear one and pack two.
Five pairs of socks – wear one and pack four.
Two pairs of shoes – wear one and pack one.
Three pairs of pants – wear one and pack two. (Can substitute one skirt for a pair of pants.)
Three shirts or blouses – wear one and pack two
One jacket and one belt – both to be worn in route.
One vest, one sun hat, and one light sweater – all to be packed.
Rain coat to be packed.
This is the bare bones packing list. You might be able to add another shirt or pair of pants – just depends on how much space is taken up with cosmetics, phone chargers, guide books, and misc.
Each of us also carries a RS Veloce Shoulder Bag as a personal item. It will hold lots of odds and ends.
This list isn’t perfect for everyone but it works well for me. It will serve as a starting point for developing your own.
We also use a combination of packing cubes, folders, and tubes to organize things and aid in the placement of the various items. One of the keys to being able to travel for a long period with only a carryon is experimenting with the packing and seeing what does and doesn’t fit and work for you.
Hope this helps as you experiment and develop your own plan.
