It happens just a few days after the third series' second half, which starred Coughlan as lead actress Penelope Featherington, debuted on Netflix.

Pop singer Sabrina Carpenter and England football player Jude Bellingham are two recent celebrities to have participated in Skims commercials.

The Irish actress made her modelling debut for the US apparel manufacturer. She is shown wearing the heather grey soft lounge long sleeve dress and the lemonade soft lounge long slip dress.

The 37-year-old is shown in a video on the official Skims Instagram saying, "Everybody's wearing Skims," over a pink, dreamy backdrop. Simone Ashley, who plays Kate Bridgerton in the popular show Sex Education, left a string of startled face emojis and love hearts as comments on one of the images.

The latest season of the Julia Quinn novels-turned-Regency-style television series centres on the romance between Coughlan's character and British actor Luke Newton's Colin Bridgerton.

Kim Kardashian, a reality personality, and chief executive Jens Grede co-founded Skims. Jens Grede has also contributed to the success of Mr Porter, an online retailer, Frame Denim, and Brady, an apparel business owned by Tom Brady.
