Prada Redline Polyester light blue Pants

I thrifted these polyester Prada dress pants, but regretted it because they are too large and long on me. They are low rise and are a chambray blue. It’s about 30 inches around the waist and 36 inches from the top of the pant to the bottom. To the best of my knowledge, these are authentic Prada. The tag inside says 42.
