This will be the first cold season that LO is walking around. I want a few pairs of fleece lined (insulated) jeans for LO. What's your favorite store for these?

Just bought a pair from Old Navy for $11! It's more than I usually spend on a pair of jeans for her but I remember last year by the time cold actually hit it was hard to find them in her size. This way worst case scenario I have one pair!
