Stiles relies on a cult-favorite concealer: Laura Mercier Secret Camouflage, $28. "You want a dry concealer that really sticks to whatever you're covering," she explains. Plus, having two colors lets you blend them for a perfect match.

Super-sharp tweezers
Stiles calls Tweezerman Tweezers, $22, the "Cadillac of Tweezers." She keeps two on hand at all times -- this way when she sends one out for sharpening (which Tweezerman does for free), she has a backup. Need more evidence that these are the best tweezers out there? Tweezerman also has a 9.5 rating on TotalBeauty.com.

Allover face color
Since Stiles lugs around a ton of products when she's working, she prefers to streamline her personal makeup bag. "I like products that do double duty," she says. Her favorite multitasker is Stila Convertible Color, $25. She says that there's a color for everyone -- and she uses it as both a blush and a lipstick.

An eyelash curler
Your search for the best eyelash curler ends here. (And if you don't think you need to curl your lashes at all, this tool will change your mind -- it works that well.) "Nothing wakes your eyes up faster," says Stiles about the Kevyn Aucoin Beauty Eyelash Curler, $20. "And I love the red rubber -- it's very chic."

A long-lasting mascara
Stiles' new mascara obsession is CoverGirl LashBlast 24 Hour Mascara, $7.99. While it doesn't claim to be waterproof, the formula really stays put -- which is as important on the red carpet as it is in everyday life. "Plus, it gives beautiful, thick lashes with just one coat," says Stiles. "But two coats is always better!"
