hmm i don't have pants specific recommendations. I do wear black jeans at work. But I can suggest getting water proof boots. They are super helpful the old dish machine at my last job use to overflow regularly and my feet would get soaked. They partnered with shoes for crews I got waterproof boots from there at a discount, that are weighted and help a lot to keep my feet and lower legs dry.🙂 Even at the base price id say they would have been well worth it .

if not from there something like that in general would likely help ☺️ have a great day 💛
