The dress, which originally retailed for $69.90, is marked down as part of a summer sale.

The Duchess of Cambridge, 39, wore the green floral Zara dress during a video call to announce the launch of a digital photography exhibition at London’s National Portrait Gallery. Middleton, who is a patron of the institution, was on the panel that selected 100 images from over 31,000 submitted for the community photographic contest, “Hold Still.”

The shots will be featured in an online exhibition of the gallery’s website starting Sept. 14.

“I’ve been so overwhelmed by the public’s response to ‘Hold Still,’” said the Duchess. “The quality of the images has been extraordinary, and the poignancy and the stories behind the images have been equally as moving as well.”

As seen in the video posted on the Kensington Royal Instagram account, Middleton’s dress features a floral print on a khaki green background. It comes with a v-neck, contrast lace trim, elastic waistband and short sleeves. What you can’t see is that it also has a daring slash to the thigh.

Just call it Zoom’s built-in modesty filter.

But there’s also another reason to recommend this dress. It falls under Zara’s Join Life label — which means it is made from at least 50% viscose. Viscose is a sustainable material made from natural sources.
