The best thing about her costume wasn't her radiant cape (old pillowcase), her flowing dress (too small nightgown), or her magic leg gear (cowgirl boots) - it was her glorious insignia. And no, it didn't stand for Super or even Sadie. It stood for SISTER!
With her boots on, Sadie knew she could do just about anything, including this whole big sister thing.
She didn't know if it was a dog, cat or baby bear cub, all she knew was that she must keep it and love it forever!
