The Gap Inc. (GPS)

Gap rose to fame in the 1990s by dressing a generation of Americans in its khakis and T-shirts, but has since been overtaken by fast-fashion chains and new e-commerce players. Its sales have declined each year since 2013, dragging down results at parent Gap Inc.(GPS), where its new chief executive, Sonia Syngal, is trying to fashion a turnaround in the middle of a pandemic.

Ms. Syngal told the Journal in May that she is using the upheaval created by the coronavirus pandemic "to refashion the company for what we want it to look like over the next 50 years."

Mr. West, who is married to media phenom and entrepreneur Kim Kardashian, has long held fashion aspirations. In 2009, he interned at the Italian fashion house Fendi. His high-end line of Yeezy sneakers for Adidas, first introduced in 2015, are released in limited quantities and quickly sell out.

As recently as 2018, he had hoped to become artistic director of Louis Vuitton menswear. After some false starts, Yeezy returned to the fashion runway this year with a show in Paris that garnered positive reviews.

At Yeezy's Cody, Wyo., studio, Mr. West has been working on perfecting the hoodie. His version is chunky and slightly cropped at the waist. "The hoodie is arguably the most important piece of apparel of the last decade," Mr. West told the Journal in March.

A version of the hoodie -- along with T-shirts and jeans for men, women and children -- will be available at Gap stores and on its website beginning next year. Prices will be in line with Gap's other offerings, according to a company spokeswoman.

Brands are increasingly teaming up with musicians and other celebrities as they struggle to stay relevant. Last year, the singer Rihanna partnered with LVMH Moët Hennessy Louis Vuitton SE to create a new label called Fenty, while Lady Gaga signed a deal with Amazon.com Inc. to create a beauty collection for the online retailer.
