What a coincidence! I was just at Kohls at lunch time today trying to figure out how to spend my gift card and saw these really cute work out outfits--if I'd had time, I would have tried some on and then put them away for my trip in December. If your yoga outfits are the same, I think they are perfect. These were Nike or Adidas brand, athletic pants--elastic waist, straight leg, with matching long sleeve t shirts and then matching sweatshirts that zip up the front. All you need is a cute pair of cross-trainers and you're good to go! You can wear the jacket in the morning, then tie it around your waist during the day if it warms up, and wear the long sleeve t, a short sleeve t or a tank top (modest of course) depending on the weather forecast for the day!
I was also thinking, if its warm enough to go on rides where you may get a little wet--Splash Mountain--who wants to walk around in damp jeans for a few hours. That work out material doesn't fit so closely to your skin, so it would dry out alot quicker!
