Aubrey Plaza triggered a two-tone boot double take at Balthazar on Monday night, wearing Ami Paris’ bicolor wedge knee-highs to the label’s Chez Balthazar dinner in New York City as Tessa Thompson arrived in the same square-toe style.

Plaza’s boots were the Anthracite Black Leather Bicolor Knee High Boots — a knee-high silhouette built on the brand’s signature covered wedge heel, which product listings place at about 85 mm. The line pairs smooth leather with a second, more matte finish and uses a square toe with a center-front seam.

The boots read as two-tone gray: one panel in smooth leather, the other in a softer nubuck-like finish running from the shaft down across the toe, with the wedge and sole kept in a darker tone. Plaza styled them over black tights, letting the split finish show fully.

The rest of her look stayed in Ami’s dark, tailored language. She layered an oversized double-breasted wool coat in deep charcoal over a black sweater dress marked with narrow white horizontal stitching at the neckline and waist. Plaza added a pop of color with a fern-green Mulberry Small Boston bag with gold hardware.

Inside Balthazar, Tessa Thompson created the second half of the boot double take. She also arrived in Ami Paris’ bicolor wedge knee-high boots, the same square-toe wedge design with a leather front panel and suede side, styled with a silky black midi skirt, gray sweater, turquoise belt and long gray coat, though in some flash-heavy photos the anthracite panels read closer to blue.

Two-tone knee-high boots have shown up more than once in New York this season. Rihanna wore Loewe’s New Comic lambskin-and-suede style — cut to the knee on a 90 mm heel with a gold donut-link ankle chain — to the “Saturday Night Live” after party in January, and Plaza and Thompson’s Ami Paris bicolor wedge boots at Balthazar added a square-toe wedge take on that split leather-and-suede construction.
