WATCH: Katie Couric gets caught with 'secret boyfriend'

Shying away from engaging in fast fashion, the star revealed that the sustainable dress had been made with fabric woven from the leaves of the Spanish red pineapple.

"To cap off Earth Day, I decided to get all dressed up in my @theolivertolentino dress made with fabric woven from leaves of the Spanish red pineapple!"

The newscaster then shared an important environmental message. "I learned in my friends @romcaz and @heatherreisman new book IMAGINE IT! A Handbook for a Happier Planet that the fashion industry is one of the biggest contributors to the climate crisis and this year I'm making a point to shop sustainably!"
