At the amfAR Inspiration Gala held at Milk Studios in Los Angeles on October 29, 2015, Alessandra Ambrosio stepped onto the red carpet in a sheer Zuhair Murad gown styled with Christian Louboutin’s “J String” pumps.
While the dramatic dress drew attention, the sharply pointed T-strap heels added the sleek finishing touch that defined the look.

Jamie Mazur joined Ambrosio on the red carpet that evening, making the appearance even more notable during a period when the couple rarely attended public events together.

The black patent Christian Louboutin “J String” pumps were mostly concealed beneath Ambrosio’s embellished Zuhair Murad gown, but the sharply pointed toe and slim T-strap silhouette added the sleek, elongated effect that made the style one of Louboutin’s most recognizable evening pumps of the 2010s.
Designed with a low-cut vamp and slender ankle strap, the “J String” balanced the sensual lines of a classic stiletto with the added stability of a structured T-bar silhouette.


Other Celebrities Who Love the Christian Louboutin “J String” Heels
The Christian Louboutin “J String” heels have graced the feet of several style icons like Ellen Pompeo, each bringing their unique flair to this elegant design.
For instance, Chloë Grace Moretz was spotted in these T-strap pumps during a promotional appearance, pairing them effortlessly with a chic ensemble. Similarly, Liv Tyler chose the “J String” heels to complement her tailored Stella McCartney suit at the 2015 British Fashion Awards, showcasing their versatility.




While the Christian Louboutin “J String” was a red-carpet favorite during the mid-2010s, the style is no longer part of the brand’s current retail lineup. Originally offered in versions ranging from 100mm to 120mm heels, the pointed-toe T-strap pump became known for its low-cut vamp, slender ankle strap, and signature red sole.
Produced in patent leather, metallic finishes, and seasonal colorways, the “J String” typically retailed for about $900 to $995 when new. Although Christian Louboutin has since retired the silhouette from regular production, it remains popular among collectors and fans of the brand’s classic designs.
As of 2026, the “J String” is primarily available through luxury resale and consignment platforms, where prices vary considerably depending on condition, size, color, and rarity. Well-preserved pairs often sell for several hundred dollars, while unworn examples can command significantly higher prices.



In March 2018, Alessandra Ambrosio and Jamie Mazur ended their longtime relationship after more than a decade together. The former couple shares two children, Anja and Noah.
