At first glance, the see-through dress Jessica Chastain wore to this Sunday’s Tony Awards looked like she needed to be extra careful in case of accidental overexposure. Turns out, it was just the opposite. “It is so fitted to me, there is no room for any kind of malfunction,” the actress told InStyle.com of her Marios Schwab design, spinning to show off every embroidered Swarovski crystal, the attached light peridot-hued necklace, and built-in corset. “And that gives me a lot of confidence. I could do aerobics in this thing, and I’m fine. That to me is a happy place that I think you need to be when you go on a red carpet.” For accessories, she chose Harry Winston yellow diamond earrings and silver Giuseppe Zanotti 5.5-inch platform peep-toe pumps. “I’m not the tallest person, so let’s hike me up—I love tall shoes,” she said. “I could really do aerobics right now.” Next time, we’ll challenge her to some jumping jacks!

Before she hit it big on Glee, Lea Michele was already a Broadway sensation, so we weren’t surprised when she told us that she plans to make a theatrical entrance at Sunday night’s Tony Awards. “For the last several red carpets I’ve done classic Hollywood glamour, but the look I’m planning for the Tonys is more modern,” Michele told us at the launch of MARKTBeauty.com in N.Y.C. last night. “My dress is very bright; I’ve never worn anything like this on a red carpet before!” (The actress will change into an ensemble that she describes as “classic Broadway” before taking the stage at Radio City Music Hall to sing a duet with co-star Matthew Morrison.) Though she works with stylist Estee Stanley, Michele told us it’s boyfriend Theo Stockman (who is currently starring in the Green Day-inspired musical American Idiot) who gets to have final approval.
