Even if the most daring stunt you've ever pulled is drinking wine out of a sippy cup during a 3-year-old's birthday party, a bold ring around your lids, like Rihanna's, tells the world, "I don't suffer fools-or insipid makeup."
Just like Kristen Stewart, when you extend liner all around the lid, including the waterline, it dramatically emphasizes the shape and color of your eyes. One caveat: If you have tiny peepers, keep the bottom line soft, and diffuse it, so you don't end up looking like a ring-tailed lemur.
To create the look at Versace, makeup artist Pat McGrath lined the inside and outside of the bottom lid, using brownish gray shadow to set the effect. If you're older than 40 and have what makeup artists affectionately call "Charlotte Rampling eyes" (dermatologists use the much less sexy term "ptosis"—aka droopy eyelids), make sure you use long-wear liner. Trust us, it's a quick, messy slide from Kate Moss to Marilyn Manson otherwise. We love Revlon Colorstay Eyeliner in black (5; target.com).
At Missoni, pro Lucia Pieroni went almost all the way around the eyes with black liner, drawing a wing on the inside of the eye and leaving the lower lid naked on the outer half. We recommend using Sonia Kashuk Small Eye Shadow Brush ($10; target.com) and MAC Eye Kohl ($16; maccosmetics.com) to score the same smoldering effect. Keep in mind: You may want to do a little pirouette with a cotton swab on the inner corners of the eyes to de-gunk them before trying this at home. Also, be sure to set the look with translucent powder like Estee Lauder Lucidity Translucent Pressed Powder (33; esteelauder.com).
