Maybe it's because Ashlee has yet to experience a highly publicized/pimped marriage crash and burn, or promote a line of embarrashingly cheap bedazzled jeans. Or maybe, it's the hair.
Ashlee is sporting a subtle, flowing wave that somehow manages to look cascading and polished. Jessica just has an out of control, fluffy, fringed disaster that she appears to be sheepishly hiding behind. Could that be why their sister roles appear to be reversed? Or maybe, it's just a great pair of heels.
