Don't Miss:

The Broadway community celebrated its biggest night of the year at last night’s Tony Awards! “Welcome to the 66th Annual Tony Awards, or as we like to call it, 50 Shades of Gay,” host Neil Patrick Harris joked during his opening monologue to the crowd of singers, dancers, actors, producers, directors, playwrights (and all of their plus-ones) huddled into New York City’s Beacon Theatre for the live telecast. First-time attendee and upcoming Broadway star of The Heiress Jessica Chastain, in a sheer Marios Schwab design, couldn’t wait to get on stage to present. “I love the Tonys,” she told InStyle.com. “This is a deal! I’ve watched it at home and I’m so excited to be here.” Other guests included Amanda Seyfried (in Givenchy), James Marsden, Jesse Tyler Ferguson, Emma Stone (in Narciso Rodriguez), and Andrew Garfield (in Louis Vuitton). See more moments in the gallery.

Celebrities love Marios Schwab! The London-based, Austrian-Greek designer and former Halston creative director launched his namesake label in 2005, and just one year later won best “New Generation Designer” at the British Fashion Awards. He made his London Fashion Week debut in 2007, and ever since, his bold, structured designs have been red carpet regulars, appearing on stars like Emily Blunt, Demi Moore, Jessica Alba, Leighton Meester, and more. “I’m interested in cultural icons—women who have made an impact in history through their character,” Schwab told us in Los Angeles recently. “There are so many women who have created that.” His signature body-conscious designs, which often feature rich materials like leather, velvet and jacquard, can be purchased at saksfifthavenue.com and openingceremony.com. If you pick up one of his creations, keep his dressing tip in mind: “The Marios Schwab girl is mystical and she likes enjoying fashion, but she also likes something that is not overshadowing her character and personality.” See who else loves Marios Schwab in the gallery!
