Although my predominant shape is hourglass, I have definite pair tendencies and feel your pain right now! I couldn't agree more with the other ladies: dresses and skirts are fabulous, comfortable and flattering. Here are a couple of examples of items I've found recently that should help me beat the heat and humidity. These outfits have both received the green light from Angie and the ladies, and I bet something similar would work for you:
1. A-line skirt with sleeveless blouse:

2. A black and white dress: I'm sure there's some poly-somethingorother in the fabric, but it's light, drapes beautifully and forgives in the right places:

These can also transition well to cooler weather with simple additions like jackets or cardigans.
I'm guessing you're smaller than me, and I imagine you'll be able to find the right stuff over time! The other girls would probably be better at recommending stores with good a-line skirt selections. Good luck and keep us posted!
