Never-worn Old Navy "Rockstar" Jeans (2/$15)

I was so happy to bring these cute pants home...but they are too tight! I'm usually an 8, but these seemed to run a bit small, so I got them in a 10. I should have tried them on before buying them; and I shouldn't have taken the tags off at home before trying them on; but I was sure they'd fit right. They don't. They're too tight on me to look flattering. Your gain, if you're a small size 8 or even a 6. Cheery red with tiny white polka-dots. Brand-new; never worn; tried on once.
