The young socialite turned reality starlet hit up the premiere of Brothers. Olivia Palermo recently went from blonde to brunette and I prefer the darker hue. It compliments her big brown eyes and flawless complexion.

So what is her secret? Palermo relies on a faithful foundation that she returns to using time and time again. Olivia told Elle magazine what was in her make up bag.

In her make-up bag is always YSL Perfect Touch foundation: ‘I’ve tried others, but I keep going back!’

She also stated that she loves Revlon mascara and Guerlain accounts for the rest of her beauty products in her bag. Currently you can catch her on The Hills spinoff, The City.
