I'm a big fan of the Olsen twin's slept-in-yet-super-chic beauty look, so when I found out they were sharing some of their best kept beauty secrets on Byrdie I may or may not have jumped for joy a little bit. While some of their tricks are somewhat obvious, others of them are a bit sneakier than I suspected!
For instance, their signature lip color? Turns out it's a lip liner! I would have never guessed. Mary Kate and Ashley are big fans of Make Up For Ever's Aqua Lip Liner in 3C.
When the twins want to jazz it up a bit, they then top that liner with Clinique's Chubby Stick in Heaping Hazelnut.
Lovelies, do you ever use a lip liner as your lipstick?
