Do these make my butt look big?

Went shopping today at Old Navy. I was looking at their spring dresses. They looked like crap on me, which was sad. However, in the clearance section I found a pair of jeans that were cheap and cute. The scary part was that they were a size and section smaller than what I have now. Section meaning they are a woman's size not a woman's plus so they are less roomie. Figured it couldn't hurt to try them on and what do you know, they actually fit! They're a little snug but new jeans are, and they aren't uncomfortable. SWEET! Also got a cute sweater to wear over a tank (thanks for the find Donna). I'm going to be rockin' the cuteness in this ensemble!
