C9 Champion Seamless Racerback Sports Bra

I was wandering around Target with my cousin, when I noticed Champion sports bras for $16.99. I love Champion, but their bras normally cost around $30.00 or more. I knew the C9 was made just for Target, but I figured it couldn't hurt to take a chance on one of these bras for such a reasonable price. Well, that didn't work out so well. I chose the bra, because I liked the fabric (nylon/spandex), the style, and the color (green). Unfortunately, the quality is seriously lacking. I am petite, and this bra is too short to stay put; it rides up. Actually, it doesn't really stay put at all; even practicing yoga causes this bra to shift. The sizing is fine (it is snug enough and everything), it is the bra itself, it is too short. You wouldn't think that would happen with a cropped sports bra, but this is terrible. Too bad because, if it would stay put, it seems like it would be supportive enough (maybe not for jogging, but for light to moderate activity). Next time, I'll fork over the extra cash to get the quality I want. Also, I like that with the full price Champion bras, you can choose your activity level (light, moderate, high-intensity), but with the Target line, that's apparently not an option.
