Levi's 517 BOOT CUT jeans. I bought these a while ago, but I'm selling them because I haven't had a chance to wear them. As you can see in the images, there's a small scratch on the hem. Description of the 517 The "517" is a popular silhouette alongside Levi's classic "501" and the fashionable tapered silhouette of the "505." The "517" is the world's first bootcut jeans, which appeared in 1971. It features a silhouette that is tight at the knees and flares out towards the hem. It was a staple item of the hippie culture after the 1970s and was popular until the 2000s. After that, smart silhouettes such as tapered and skinny became the trend, but with the recent revival of retro booms like the 90's, Y2K, hippie, and vintage clothing, it's gaining popularity again.
