If you've checked out the January issue of O Magazine, you've seen Oprah in a purple athletic outfit that flatters her shape, even though she's nowhere near the shape she desires. The clothes she's wearing are from Beyond Yoga, a line that has gained quite a few celebrity fans ... of all sizes.

Beyond Yoga is designed by Jodi Guber, who I had a chance to chat with recently -- you can read more about that at StyleList. What really struck me about Guber is her dedication to creating comfortable but stylish clothing that work on women from size XS (like Gossip Girl's Blake Lively) to XL, like Oprah.

Guber has been a devotee of yoga, as well as an instructor, for many years, and has also been in the public eye since she was a child due to well-known parents. However, she was overweight, which made her uncomfortable at the time but led to her determination to make sure even those of us who don't fit in a Small can look (and feel) great.

In addition to Oprah, famous fans of Beyond Yoga include Cindy Crawford, Charlize Theron, Reese Witherspoon, Jamie Lee Curtis and many more, all of whom tout the mix of comfort and style.

From shorts and bras to pants and jackets, Beyond Yoga has a variety of styles to suit your active lifestyle -- and while it's a higher-end line, you can find plenty of pieces on sale on their website.

Even if you're planning to lose weight (maybe you're even taking part in America Takes It Off -- click on the badge below for details), it's important that you have clothes that flatter the body you have now -- you'll have more confidence, which will keep you motivated on your weight-loss quest!
