This month, the renowned New York jewellery designer has tapped 93-year-old fashion icon Iris Apfel and 18-year-old fashion blogger/editor turned-actress Tavi Gevinson for his Spring 2015 campaign.

Both ladies look dazzling while decked out in glittering Alexis Bittar pieces for the portrait-style images shot by Terry Tsiolis and styled by Arianne Phillips. Constantly pushing the envelope, Bittar is known for setting new unorthodox standards when it comes to standards of beauty and agism.

"In terms of the fashion industry, we're selling to women who are predominantly over 35, but we're showing them images of girls who are 19 and retouched," Bittar told WWD. "For the campaign, we honed in on the essence of strong women who haven't conformed. Tavi is so strong and so bright. Iris is kind of like a mother to me at this point and was probably a little bit annoyed that I never asked her to be in an ad before."
