People have been wearing our 501® jeans for 150 years. And along the way, we’ve introduced quite a few different versions to the portfolio. From the OG, to the ’93, to the revival of the ’54—this legendary fit has done its best to change (and look better) with the times. Below, we break down the details of each fit to help you pick the one that’s right for you. (Just don’t be surprised if it becomes impossible to choose just one favorite family member.)

Every May, we celebrate the anniversary of Levi’s® first-ever blue jeans. But this May is something special. This May, the most iconic denim in the world turns 150 years old. It’s our 501® Sesquicentennial (dare you to say that one time fast). Now that’s cause to party.

Get to know real members of Levi’s® design team (plus a special guest)—who they are, what they do, where they find inspiration. This season, the design crew honors the 501® Original’s biggest anniversary ever with a collection celebrating 150 years of handcrafted self-expression.

This year, we celebrate a century and a half of the 501® Original (our first-ever blue jeans) and people living in Levi’s®. And in the world of 501® jeans, every person has a pair, and every pair has a story. What started with some denim, copper rivets and an American dream has become a worldwide phenom and, quite possibly, the most beloved clothing article of all time.

It’s not often life gives you the opportunity for a do-over. So when it came time to launch a fresh fit for the 150th anniversary of our 501® Original (aka our first-ever jeans), we loved the idea of releasing brand-new jeans that are actually based on really old jeans. And not just any old jeans. Old jeans with a look that’s totally vintage *and* totally modern. Old jeans with a fit that rounds out our current 501® lineup. Old jeans with a contentious past involving hate mail, alligators and one of 501® jeans’ most iconic attributes. Intrigued yet? Below, we give you the rundown on our new(ish) 501® ’54 Jeans, and prove old-fashioned has never looked better.

The 501® is one of our most famous fits, there are no bones about it. Its hundred-plus-year history literally put blue jeans on the map. And even though the original was a rough and tumble workwear pant, its easy wearability and durable construction quickly made it a fan favorite during off hours as well. So it's no wonder you already know what is arguably the most iconic denim style of all time. And because of its enduring fame and international reach, it only makes sense that we get a lot (and we mean a lot) of questions about the 501® fit itself, and the 501® fit family. “Woah woah woah,” we hear you say, “what is a fit family?” Well, let us tell you. Here at Levi’s®, we don’t always need to reinvent the wheel. Sometimes it's little tweaks that make all the difference—lengthen a hemline here, give a little more room in the seat over there—and voila suddenly you have a whole new look, but not a whole new fit. Enter fit family. The slouchier version of the 501® is not the 502, it’s the 501® ’90s. But what are the key differences that define each of these 501® variations? We break them down below to help you find the one that’s right for you.

You already know our iconic 501® fit—and with its 100+ years of history, how could you not? But do you know the whole family? Or even what a “fit family” is? Welp, here’s your chance to learn. Let’s start with the 501® fit. It’s the one and only original blue jean. It debuted over a hundred years ago as a workwear pant but slowly worked its way into the cultural zeitgeist as a downtime symbol of casual cool. It’s literally the blueprint on which all modern denim is made. Suffice it to say it’s kind of a big deal. So if the 501® is a fit, then what is a “fit family”? The fit family is all of the styles that are built as a variation of that original fit. For example, make the 501® Original just a little slouchier and you’ve got the 501® ’93 for men. So just think of the fit family as a collection of little tweaks here and there that put a fresh spin on a classic well-loved fit. Now to the 501® fit family. What are the little tweaks that make a big difference in these 501® variations, and what version of the 501® is right for you? Read on to find out.
