I am in need of an emergency pair of dark wash bootcut jeans and Old Navy seemed like a good place to look to get the right rise, length, and price. Here are my ?'s:

• What's the difference between the Sweetheart and Goddess styles? One says "high rise" and one says "classic rise." Is one higher than the other? Is one more fitted? I'm confused...

• How do they wear? Do they grow?

• How do the sizes run? I only own some ON loungewear in an XS. I'm confused by the addition of a size 1, which appears to be the only odd numbered size. I can't decide whether I'm a 0, 1, 2, or 4. And if they grow, I may need to size down.
