Pix: Lipstick secrets of Katrina, Sonam!

Love me, love my lipstick.

If summer-time cosmetics are all about vibrant hues and garden-fresh looks, fall fashion embraces the dark side with its penchant for muted tones and severe style.

If popular glossies are to be believed, dark lips are the 'in' trend. This autumn, pucker those lips and paint them in irresistible shades of blistering browns, marvelous maroons and passionate purple.

Curious to see how it's done? Take a look at the sexy September cover girls of Bollywood:

Katrina Kaif, Elle

Taking a break from her trademark pink, glossy lips and teenybopper clothing, the Mere Brother Ki Dulhan hottie works up some old Hollywood glamour with a rich burgundy pout, classic curly tresses and a resplendent sequined gown.

From black to coral, she's donned it all. And now the constantly trendy Sonam Kapoor dabs on an intense shade of cranberry to remind us why she's a fashionista for every mausam.

The half-Pakistani, half-Czech stunner from New York is making waves in Bollywood ever since Imtiaz Ali cast her opposite Ranbir Kapoor in Rockstar.

While we cannot vouch for her acting skills yet, the babe sure knows how to pull off a pair of deep, dark ruby lips.

Known for her soft focus allure, Ms Sharma does a complete 360 degree with her feisty and sharp avatar in Grazia's September issue.

One long look at her cocoa brown lips is enough to burst into that groovy Mocean Worker ditty, Tres, Tres chic.
