Melissa Doyle in leather dress at opening night of Agatha Christie’s The Mousetrap

Melissa Doyle was feeling anything but mild on Sunday night.

The TV host left her understated duds for an eye-catching leather dress for a theater event.

The 52-year-old led celebrity arrivals at the premiere of the 70th anniversary production of Agatha Christie’s The Mousetrap at the Theater Royal in Sydney.

Melissa showed off her figure in the wrap dress, which fell tight around her waist and had a modest slit at the calf.

The plunging neckline showed off a hint of bust, and she added a pair of patent leather heels with a pointed design to the look, as well as dangling earrings.

The former Sunrise hostess opted for a soft makeup look with a pink blush and a pale pink lipstick while wearing her blonde locks down and straight.

Also making waves was actress Suzan Mutesi who made a statement in a bold gold dress with a hip-high split and a large cutout at the midriff.

The glittering dress had a one sleeve design and the other was exposed, and she paired it with iridescent heels.

The 36-year-old opted for a bold makeup look with bright red lipstick and added statement earrings to her ensemble.

Amy Castano kept things tight in a black suit and went braless under a blazer that she paired with split wide-leg pants.

She completed the look with a micro purse and strappy black heels with rhinestone accents.

Theater superstar Lucy Durack channeled old Hollywood in a black wiggle dress with a plunging neckline and puff sleeves.

The 39-year-old wore her blonde locks in a Marilyn Monroe-inspired curl and kept her makeup soft with a pink lip gloss.

The drag queen, whose birth name is Ben James, added black lacquer Mary Jane heels and tights.

The 28-year-old opted for a dramatic makeup look with heavy liner, burnt orange blush and wine lipstick, and wore rhinestone clips in her hair.
