Doesn't she look smashing? This is a really nice example of how some brunettes should just stick to a rich brown instead of gradually lightening their hair, shade by shade, balayage by balayage, and ending up way too close to blonde for it to suit them.
Darker hair really works for Khloe, and she dresses perfectly for it in a cream mini skirt and noticeably less fake tan than usual.
Three gold stars for you Khloe, you're looking much more natural and more beautiful.
