Patagonia Fleetwith romper fading/damage to material

I have the chance to buy a Patagonia Fleetwith romper for 60% off. There is considerable damage to the material on one of the legs. It’s not a stain or bleaching, but a fading of the color in several spots. I don't know if it’s from sunlight or being clipped/clamped a certain way. I’m hesitant to purchase as Im not sure this is fixable?
