Coated Finish Dark Purple Dyed Skinny Pants

These are a dark purple eggplant color. These sat in my closet for years. I am afraid to ruin them in the wash and ruin the dye with the finish. They haven’t been worn. They have stray hairs and lint because they were stored with my other clothes that tend to attract a lot of dog hair. It says it can be washed in cold water on a gentle cycle, but I have ruined many clothes before.
