As Spanx celebrates its 25th year, the company has partnered with La Ligne for a limited-edition capsule collection of luxurious cashmere and wool sweaters.

At the center of this milestone collaboration is a campaign featuring award-winning actress, founder and chief executive officer of Pattern Beauty and style icon Tracee Ellis Ross, photographed by Olivia Malone.

“For our 25th anniversary, we are celebrating iconic women. Partnering with La Ligne, another female-founded brand, was a natural fit, and bringing Tracee Ellis ross into the mix made it magic. Tracee is the ultimate icon, fearless, a style visionary and a true trailblazer, which is exactly what this collection represents,” said Katie Weeks, vice president of brand marketing at Spanx.

“Spanx started reinventing shapewear 25 years ago, and we have never stopped innovating. Today, women come to Spanx for best-in-class shaping bottoms, and this partnership with La Ligne introduces limited-edition luxe sweaters that complete the foundation of her modern wardrobe,” she added.

“We are thrilled to partner with Spanx on this capsule collection, which so beautifully merges our shared values of confidence, versatility and timeless style,” said Meredith Melling, cofounder and chief brand officer of La Ligne. “La Ligne was founded on the belief that the perfect wardrobe starts with pieces you can wear every day, elevated with effortless style. These sweaters are designed to do just that — luxurious essentials that pair seamlessly with Spanx’s innovative foundations.”

The Spanx x La Ligne capsule features six ultra-soft cashmere and wool blend sweaters, designed with La Ligne’s signature sophistication and Spanx’s modern sensibility. Each piece was created to style seamlessly with Spanx’s newest innovation: the SPANXshape Authentic 360 Corduroy collection, combining luxury knitwear with Spanx’s celebrated approach to flattering, comfortable bottoms.

Three of the pieces feature La Ligne’s signature Marin stripes in black and camel; cassis, Spanx red and gray, and light blue, cassis and Spanx red. Two of the pieces come in solid colors camel and Spanx red, and each sweater features custom Spanx red tips at the cuffs.

Prices range from $350 to $450.

The capsule is available starting Wednesday on spanx.com and lalignenyc.com.

The digital campaign will run across Spanx and La Ligne’s digital and social channels.
