Every time these threads come up I say the same thing. For most cleaners the best advice is to lose the Velcro shoes, quit pulling your pants up to your neck (over the belly), and quit using your shirt as a coffee sponge/napkin. One other thing, maybe don't be 80 pounds overweight and shower every morning. I'll go to my grave saying it's not so much what you wear but how you present yourself. I guarantee I can go in to a house with khaki shorts and a dry fit embroidered t shirt, and look every bit as professional as the hack in dress pants. It's how I (or you) can present yourself, are you knowledgeable, can you carry a conversation, are you an EXPERT!!!! Keep it simple, be comfortable, and don't be an idiot!!!
