Emma Stone sure knows how to glam it up, doesn't she? At last night's GQ Men of the Year event in LA, the actress wowed in this subtle lavender shadow. Encircling the eyes with makeup can look raccoon-like, but Emma manages to pull it off, thanks to a light touch and a soft-toned shade. The great thing about this cooler-toned shade is that it looks great during all seasons, and it just happens to be very of-the-moment. You can look pretty in purple shadow, too. To get some tips on wearing it without looking Grimace-y, just keep reading.

• Lite-Brite: As a general rule, the darker the skin, the brighter you can go with the shade. The lighter the skin, the lighter you can go. However, avoid choosing too light of a shade, which can wash you out.
• Green-Eyed Girls: Purple-based shadows make green eyes pop. Lavender, lilac, violet, mauve, and plum are all perfect options. A subtle pinkish-purple will help to bring out the gold tones in green and hazel eyes.
• Don't Feel Left Out: Due to the yellowy-orange undertones that brown-eyed girls have, purple shadow creates a beautiful contrasting option. For those with blue eyes, go for a purple shadow with bronze or brown undertones.
• Don't Take the Red Eye: Avoid reddish purples or purples with intense pink undertones, which can cause an unwanted I-haven't-slept-in-days effect.
• Light-Handed: To prevent a garish look, keep your application light. Think more along the lines of a sheer wash of color.
• Afraid of the Purple?: Opt for a fun purple liner instead, like Victoria's Secret Liquid Glitter Liner in Plumburst ($7). For a more refined look, try MAC Technakohl Eyeliner in Purple Dash ($14.50), a beautiful aubergine, or Victoria's Secret Mascara in Violight ($7).
• The Rest of Your Makeup: When wearing purple, keep the rest of your makeup in the same color family. Avoid extreme lips and warm-toned bronzer for the most flattering finish.
