If all you have to do in life for yourself is shop and look good and you're pretty much in charge of your own schedule regarding even that. Who can't look good? That's your job.
Look how beautiful Oprah looks each and everyday on her show. She's working everyday and probably up early everyday and still looks beautiful at fifty and some. She has help. Help from Andre and whoever else. All the help she needs.
Now how could Paris, less than half Oprah's age, not look good everytime she steps her foot outdoors? Her schedule is a lot less hectic and demanding. She's got at least as much "help" at her fingertips, and she's naturally beautiful and young. She'd better look good. That's her job, isn't it?
