IK -- I *so* sympathize with this. I hate dressing for our summers (very hot, very humid). When I was working in a school district, of course all the school buildings built before the 1970s were not air-conditioned, since the reasoning was that no one was there in the summer anyway. Enter global warming, extended school years under No Child Left Behind, and the fact that in my district the psychologists came back to school a week before everyone else in August and stayed a week longer in June, and you get a complete recipe for disaster: trying to dress professionally while sweating and frizzing in the breeze from a tiny fan sitting on your desk.
Ugh.
And the whole "dress in long, light layers" idea always works better for me when I'm actually in the sun, not when I'm sweltering indoors.
If I were you, I would just get a pile of lightweight tees that can then become layers when you get to a less hostile climate. I've had success with these: http://www.landsend.com/produc.....-t-shirt/i A zillion colors and sizes, wash and wear, and not so scooped that you're forced to wear a cami (Hello, tee shirt manufacturers! No one wants to wear a cami under their clothes when it's 103 with 90% humidity.)
Can you pin your hair up in a dramatic clip? http://shop.nordstrom.com/s/fi.....t& That's about the only thing I can think of to doll things up. Too hot for most jewelry, I imagine.
