Hendricks admitted that she can actually go braless when wearing Siriano's "well-constructed" dresses, and she certainly convinced us with this figure-flattering black number. It looks as though it was made perfectly for her hourglass shape, and the lace straps cover up her cleavage just enough.
We also love what the Best Supporting Actress nominee did with her hair. Stylist Gregory Russell used Vidal Sassoon Pro Series Waves Hairspray to recreate '30s-inspired waves with modern texture. And that red lip adds the finishing touch to Hendricks' retro glam.
