Work shirts and trousers only. But I don't have that problem any more.
Weddings, funerals and similar very special occasions only now.
Seems to me the rest is done simply to fill people's time and for them then to complain about how their life is filled by chores and they don't have time to lead their own fulfilling life!
Dust, I'm not allergic, so just roll it up into a blanket once per year.
We did have a young bloke at work who bought the best quality 100% cotton shirts, never ironed them, and never tucked them into his trousers. Looked at absolute mess but should I really judge him by his appearance? Contrarily, does a slovenly attitude to dress equate to a slovenly attitude to life in general i.e. quality of work? Discuss!
