I found this great website which caters for sizes 0-28, but specializes in the 12-28 size range. (What the hell is a size 0?!) The clothes and accessories are amazing and the choices endless, plus the prices are very reasonable! Visit www.torrid.com to see the goodness for yourselves! Oh and be sure to check out their extensive Denim collection; Baby Phat, Apple Bottoms and Z.Cavaricci all sell their jeans there...
Note: They have a 'Summer Sale' on right now with items as low as $12.00!
