First of all - welcome to the forum!
I have seen painters working on houses around here that have been wearing "normal" clothes and I have to say they look a bit - well - amateurish.
We all have certain ideas about dress codes and uniforms. It makes us feel comfortable and respect the person wearing it. For example, if you saw the surgeon, who is about to operate on you, as you were taken into the operating theatre wearing old jeans with holes and a smelly teashirt, would you have the same confidence in him as if he were in his scrubs?
Would people respect a policeperson the same if they just had a badge on the lapel of their cardigan? would you have confidence in your barrister in court if they turned up in casual clothes?
I have nothing against dressing down (or up in some cases) as we are all individuals underneath and what we wear doesn't in anyway affect our ability to do the job.
However, I can't help feeling completely comfortable with our painter who has access to the most personal spaces in our house, because he wears the traditional whites and is proud of how he looks. I don't think I would feel the same if he were dressed differently - but I haven't tried it - to be fair.
I would stick with the whites.
These days there are lots of people who take a short course in painting and decorating at college and set themselves up in business - they are normally the casually dressed ones. Here today, gone tomorrow types that don't have the same professionalism and attention to quality as you obviously do. Be proud of what you are when you walk down the street. It is your best advert - apart from a nice, sign written van parked outside people's houses whilst you work.
Be happy when people smile at you - and then give them one of your poshly prepared business cards and ask if they need any decorating doing. Cheeky and professional is a great combination
