Wearing "white" makes you look professional!! Use a rag not your pants! I always wear CLEAN i.e. not full of paint, whites. When the get dirty I use them for outside work The BEST brand most durable and comfortable brarand for me is CARHARTT Painters Drill pants/shorts. (Some compaines around here do not let there painters wear shorts even in the summer). Carhartt also makes a double knee for more durability in the knee and the bib overall, yuck!
Also, BIG BEN PAINTERS DUNGAREE are very durable pants. I still have a pair over 10 years old
One day a friend showed up to work with his new $8 Home Depot white, they ripped within hours! He had to leave early, he did not have an extra pair in his truck. Dickies are awful!!
