From my recent trip I took with my family I would say something comfortable and light with a jacket and shoes you can easily take off since the security in the airports are hectic. I made the wrong choice my wearing a sweater in the Houston airport while coming back from my trip, even in the airport I was feeling drained! I guess that's what happens when I come back from a country that is in winter.
On top, wraps rule for me. I usually wear either a cotton blend tank or t-shirt with a wrap over top. This way, when it's too hot I leave it draping open and sleeves shoved up. When it gets colder, I wrap the front ends around myself and pull the sleeves down enough to cover my entire hand. On bottom, I usually wear black leggings or black yoga pants. On my feet, I wear either soft leather flats or ugg boots (the latter ugly but very comfortable). I say the rule of thumb is to KEEP IT SIMPLE.
the story of my life.
long or short haul its usually the same unless i am coming straight from an appointment.
*free city sweatpants (so i can sit like i want on the plane)
*jersey cotton tee (so it is not itchy)
*warm hoodie (so my head wont touch any parts of the plane )
*cashmere scarf (so i can wrap it around my neck to prevent gross plane air)
What do I wear if I'm crossing over from a hot country (Oz) to a cooolldd one (US)? In-between clothing? I've got no idea! What's comfy (the most important factor) and decent looking? I don't wait to boil alive in the plane but I certainly don't want to freeze my [imaginary] balls off at the airport either!
I hate to say it but UGGs (for the extremely cold plane rides) and sweatpants and tees are the best way to go.
The last time I went on a plane I wore a short-sleeved dress and Christian Louboutin wedges, my feet were blue and my arms were freezing.
