Original 1960s Levi's 551ZXX W34 L30 Waist: 43cm Inseam: 74cm Leg opening: 21cm Thigh width: 31cm Rise: 31cm Total length: 102cm 551Z XX: A slim-fit zip-up model manufactured for five years, from 1961 to 1966. (The 551Z did not have a leather patch.) Due to a model number change in 1967, the 551ZXX became the 505. The 551Z is the first men's jeans from LEVIS to use "PRE-SHRUNK" denim. Specs: Red tab BIG E, paper patch, GRIPPER ZIPPER zipper, top button back stamp K Silhouette: Straight Denim color: Dark indigo As the photos show, there is bleaching and repair. The silhouette when worn is truly worthy of being described as "the most beautiful in the world." If you plan to wear them, in my personal opinion, they would be perfect for someone with a standard build, 170-180cm tall. Of course, they are also recommended as a collector's item.
