Hello, size XL for our Claret Red Wide Leg Muslin Women's Trousers model MG1980 generally corresponds to the size range 42-44. Suitability for 85 kg depends on your body measurements and the fit of the trousers. This model generally offers flexible use because it has wide legs and a comfortable cut. However, to ensure the most accurate fit, I recommend comparing your waist, hip, and height measurements to the size chart on the product page. If your measurements match the XL values in the table, you can easily choose it for 85 kg. If you want more detailed information, you can contact our customer service. Best regards, Deniz Madmext Team
