Don't Miss:

The first day of New York Fashion Week is underway and the stars are out to celebrate. Nicole Richie showed off her House of Harlow collection at Bergdorf Goodman last night, Solange Knowles spun tunes at Macy’s Bar III pop-up shop, and Matthew McConaughey played cheerleader to wife Camila Alves at the Heart Truth’s Red Dress show. And, of course, the new fashion collections proved to be chic—painter-like prints popped at BCBG Max Azria, glitter eye makeup appeared at Vena Cava, and that’s not all. Click through the gallery for everything you need to know about day one at New York Fashion Week.

The dashing movie star works a slim tux in the campaign for Dolce & Gabbana’s new fragrance, The One Gentleman ($57/1.6 oz, macys.com). Only we can show you these exclusive images from the shoot and share what the actor had to say about being a modern gentleman himself. Click on the gallery below to see more!

Dolce & Gabbana celebrated 20 years of designing men’s collections with a star-studded exhibition following their Spring/Summer 2011 Menswear runway show. Guests like Chace Crawford, Rachel Weisz, Matthew McConaughey, Camila Alves and Morgan Freeman, all clad in head-to-toe Dolce & Gabbana (right down to Freeman’s gloves), sipped on the designing duo’s new cocktail, Martini Gold by Dolce & Gabbana, and watched highlights from two decades of shows, plus pop-up images from both recent editorials and ad campaigns. While our favorite look of the night was Weisz’s tulle bordeaux strapless cocktail dress, we can’t wait to see what Dolce & Gabbana has in store for men for the next 20 years!
