Think Bebe Sport looks.
Wear some comfy spandex/cotton pants, a tank with spandex/breathable material, and a lightweight water repelled jacket.
The shoes you wear should be comfy too. Also flexible.
Since you are going to be hiking, you should really wear a jacket with a tank underneath. If you get hot you can tie the jacket around your hips, and sport the tank top.
Seriously, if you go to Bebe Sport, you will be able to find the complete outfit, even the shoes!
I don't know if you are gonna wanna get the Bebe shoes dirty, but if anything, you will be able to find the pants, tank, and jacket there.
For a cheaper option, go to Target.
They have a great workout section, with matching bottoms, tops, and tanks.
Also, try and carry a fanny pack.
They sells these at Bebe, but probably also can be found at Target, or Wal-Mart. You can put your water, or granola and cell phone in the front, its better than stuffing in pockets which can drop, or fall out.
Good luck finding the clothes, I think you will be OK with the stores I suggested.
Have fun, don't break anything!
Stay fashionable!
