The veteran actress, 76, has turned back the time for the modelling shots, in which she emulates the 1980s glamour she was famed for during her stint as Alexis Carrington Colby on U.S. TV soap Dynasty.

And Collins admits she jumped at the chance to pose for Bittar's cameras because she is a big fan of elaborate costume jewels.

She says, "I don't collect real jewels, as I travel so much, but I have a vast selection of costume jewellery since I was a teenager (sic).

"Alexis Bittar is by far my favourite costume jewellery designer. His whimsical designs suit my personality effortlessly. I always feel glamorous and sexy whenever I adorn myself in his creations."

Posters for the new advertising campaign were launched in New York this month (Feb10), to coincide with the city's Fashion Week, which kicks off on Thursday (11Feb10).
