A few months ago I read about Zafu, a website that helps women find the perfect fit in jeans. Though I was initially skeptical, I was impressed when it matched me up with my favorite jeans source, Eddie Bauer. However, Zafu was suggesting a different style of their jeans; I ordered them, and they were perfect!
If you are a fashionista who must have jeans that are both stylish AND suited to your body, this is definitely the site for you. In addition to the jeans analysis tool, the site is full of great articles about jeans...and bodies, including a fit dictionary. Yes, "whale tail" is as bad as it sounds.
