Natalie Portman’s “Good Sex” shoe lineup just gained a heritage icon: Gucci’s black horsebit loafers, styled with ribbed white crew socks while filming in New York City on Monday.

The Italian-made pair featured smooth black leather uppers, an almond toe and a low stacked heel. Across the vamp, Gucci’s gold-toned horsebit hardware — designed by Aldo Gucci in 1953 — added a polished, equestrian inflection that’s stayed intact through seven decades of reinterpretations. The socks sharpened the contrast, giving the silhouette a practical, downtown edge.

The rest of Portman’s look leaned into ease: a lightweight beige trenchcoat left open over blue-and-white striped shorts, a burgundy baseball cap and a black leather shoulder bag.

It’s the latest entry in an on-set shoe streak that’s been quietly mapping out the 2025 office core and corp core mood boards. In recent weeks, Portman’s character has cycled through white leather Celine mary jane pumps, patent black Oxfords worn bare-ankled and a loafer-ballet flat hybrid with an extended vamp. Each choice has toggled between masculine tailoring cues and feminine polish; the horsebit loafer bridges both without blinking.

The style’s longevity speaks for itself. Gucci marked the horsebit’s 70th anniversary in 2023 with a Milan exhibition, Gucci Horsebit Society, showing the design’s evolution over the decades. Its core appeal — a balance of formality and adaptability — has made it a fixture from Ivy League libraries to front rows, and now, fictional Manhattan therapy offices.

Whether she’s in pointed heels for high-stakes scenes or flat Oxfords for moments off the clock, Portman’s “Good Sex” wardrobe keeps returning to footwear with purpose. Gucci’s horsebit style simply brings that narrative into a lineage 70 years in the making.
