From the jail cell to the red carpet!

The stars of "Orange is the New Black" traded in their prison jumpsuits for glamorous gowns at the 2015 Emmy Awards on Sunday night in Los Angeles.

Laura Prepon was the first celeb from the show to arrive at the big show, showing off her curves in a figure-hugging red dress with a gold and black bolero. She paired her bold ensemble with a chic updo, smokey eye makeup and a pink lip.

Laverne Cox stole the spotlight at the star-studded event, showcasing her killer bod in a turquoise Calvin Klein Collection dress with cutouts along the back. The actress completed her show-stopping ensemble with perfectly tousled waves, nude lipstick and yellow stilettos.

Danielle Brooks also added a vibrant pop of color to the red carpet in a pleated yellow, turquoise and blue chiffon halter dress, which she paired with a sleek ponytail.

Meanwhile, on-screen couple Matt McGorry and Dascha Polanco posed together at the event. The actress put some serious cleavage on display in a dress with a yellow top and dark sheer skirt as her TV beau looked dapper in a black suit.

What do you think of their transformations? Pretty crazy, right?!
