Great thread! I love to travel and hear about how other people do it!
What do you usually wear on planes?
I am always SO COLD on planes, so I dress warmly in layers. If it's an international flight, I wear Juicy fleece or velour pants (no logos!), a t-shirt or tank top, a long-sleeve shirt over that, a hoodie and flip flops (I bring extra-warm socks!). That way I can be super comfortable for the long haul!
If it's a shorter flight, I usually wear jeans, some kind of shoe that slips on and off easily like flip-flops or ballet flats, a t-shirt, and a hoodie.
If it's a shorter flight and I have to look decent while traveling or immediately upon arrival due to business, I wear a black t-shirt dress and bring a huge pashmina which can double as a blanket.
What do you take with you?
I bring lots and lots of books (due to the amount of books I haul, I usually try to bring paperbacks!) and magazines, which are great readying material because you can easily discard them once you're through (unlike books). I also take along my iPod Shuffle and a journal.
What purse do you carry?
Sometimes I bring my Chanel Grand Shopper because it holds so much, but it is very heavy and not too wieldly. A better plane-purse is my medium Longchamp Les Pliages tote... super lightweight, folds up into nothing, and squishes under the seat or overhead in the cabin.
What is in your purse?
Makeup bag, glasses, spare set of contact lenses, cell phone, keys, a couple books and magazines, iPod shuffle, journal, pen.
