I purchased these denim jeans in Dubai, but I'm selling them as I haven't worn them. 1. Model Number: 501 '81 • Levi's "501" is an iconic jeans model with a classic straight fit, loved by many fans for many years. The distinctive part of these jeans is the design based on the 1981 version, as indicated by "501 '81". The 501 of this era is characterized by a high waist, a relaxed hip, and a roomy thigh area. Also, the tapered leg (design that narrows towards the hem) is a feature of this model. 2. Material: 100% Cotton • These jeans are made of 100% cotton. This is the basic material for denim and has the characteristic of being durable and long-lasting. Old Levi's jeans were made of this kind of stiff denim. 3. Red Tab • The red tab in the photo is a symbol of Levi's and indicates that the jeans are genuine. The red tab in the photo says "LEVI'S," so it is understood to be a regular Levi's model (unlike "Big E"). 4. Patch • The "501 '81" patch has the words "Genuine Quality Clothing," emphasizing that it is an original Levi's style. This patch is a traditional design of Levi's jeans and guarantees the quality and durability of the denim. Age Estimation: These jeans are a model that reproduces the style released in 1981, but judging from the tags and construction, they appear to be a recent release. Especially from the expression "Responsibly Made," there is a high possibility that it is part of a modern sustainable product line. Summary of Features: • High waist, relaxed hip and thigh, tapered leg • 100% cotton with a stiff feel • Red tab and patch symbolize the original Levi's Silhouette: Straight
