I just wear my normal clothes, but I always wear a clean apron. I used to wait tables in a restaurant that only required us to wear an apron as our uniform. It was great because wearing my own clothes was comfortable, but the aprons made all of the servers easily identifiable to the customers, gave us a place to carry our stuff, and helped keep our clothes clean underneath. I think wearing an apron looks more professional than just wearing plain clothes. I want to be treated like a professional, but I also enjoy establishing a somewhat personal relationship with my customers. The apron sort of goes along with that I suppose. Plus, it gives me a place to stash all of my stuff. I keep my wood cleaner and all surface/glass spray in pockets at the front when I do all the dusting, along with several types of cloths stashed into the apron strings around my waist. I also keep that stuff there when I vacuum, so if I noticed I missed something while dusting, the tools are right there. Also keep my long dusting wand stashed in the apron strings. You can get an apron with your logo on it at care press for around $20.
