I bought these about three years ago and wore them about three times, but I've had them in my closet since then, so I'm selling them. Regarding the size, according to ChatGPT: The "6045 / 330 / 800 / 44" part, the "44" indicates the size. For ZARA men's pants, this corresponds to EU size 44, which is generally equivalent to a Japanese size of approximately 76-78cm waist (equivalent to a size S). Please feel free to ask if you have any questions!
