The number 16, for example, holds a special place in the life of young actor Matt Damon. Fortune cookies provide some people with luck, while others attain spiritual elevation through their angel numbers. The classic Levi's 501 is, of course, the wonderful old 501 (and remember to always rock this iconic American garment).

Next year, Levi's 501 jeans celebrate their 150th anniversary, and the American denim brand is already in party mode with a star-studded campaign called "The Number That Changed Everything," which promises to reveal "the million dollar number" that changed everything.

To commemorate the brand's 501 denim's timelessness, Levi's invited a slew of tastemakers who represent the creative energy generated by its iconic form.

The collection's imagery is filled with culturally deconstructive figures such as Kid Cudi, designer Tremaine Emory, musician Mike D of the Beastie Boys, model Nathan Westling, creative director and model Gia Seo, The Paranoyds' Staz Lindes, and stylist and editor Gabriella Karefa-Johnson.

The 501 has been updated with a new "90s fit" by Levi's, which isn't satisfied with simply repeating the old cut. The relaxed, baggy style of this version is reminiscent of a more casual time, when clothes were more carefree and simple to wear.

The two brands seem to compliment one another. The designs are likewise rooted in the brand's more recent history, which includes a range of branded tees and denim jackets that harken back to pre-Y2K style.

"With denim, nostalgia may provide both attractiveness and comfort," Karyn Hillman, the Chief Product Officer at Levi's, added. "We want to preserve the new 501 '90s jean's aim is to capture what we call a "favorite worn-in pair of jeans from the past." A little more laid-back, midrise, and with just enough bagginess in the leg—simple, easy, and cool."

This isn't even the first time in recent memory that Levi's has enlisted big names to commemorate its illustrious clothing: just last year, it celebrated 501 Day with Naomi Osaka and Jaden Smith.However, there is one number that has had a bigger impact on the global retail industry than any other - and it's still right at the top of its game.
