We were pretty certain that we had Hillary Clinton‘s signature style pegged down. After all, the former presidential hopeful made the pantsuit her go-to look throughout her 2016 campaign, with endless think pieces dedicated to how she had reinvented the look for impassioned feminists.

This week, however, she made the case for an entirely new look: the formal caftan. Stepping out for the wedding of campaign supporter Marc Lasry’s daughter Sophie and her hedge funder fiancé Alex Swieca in NYC, the former First Lady was pictured wearing a pale blue caftan. (Side note: also in attendance was Donald Trump‘s youngest daughter Tiffany — we’d love to have been a fly on the wall if these two had locked eyes across the dance floor).

While you might think that the voluminous dress is usually restricted to beachwear, it is a garment that is reserved for royalty in some cultures (Queen Hillary, anyone?) and originated as a formal garment worn as a dress coat. Indeed, in the 1950s, Dior and Balenciaga introduced caftans into their evening-wear collections, while American hippie culture in the 1970s popularized the item thanks to the movement’s love of Moroccan culture. The caftan’s biggest moment perhaps came in 1975, when Elizabeth Taylor wore one for her second wedding to Richard Burton.

But anyway, we digress. Of course, we’ve seen Hillary in a dress before during her years attending glamorous black tie events as the First Lady to then-president Bill Clinton, but it’s certainly been a while since we’ve seen her without her trusty pantsuit. Are we on board with the new, floatier, funner Hillary? The jury’s still out. But we’re glad she’s happy, nonetheless.
