No customer worth having anything to do with is going to give a toss what you're wearing.
Squeaks,
You're dead wrong here.
I've worn a uniform all my working life, firstly for 17 years in the army, then as a window cleaner. Perception and first impressions count; fact.
I'm sure that when Wor Lass and I turn up to quote for a property that the customer firstly feels safe because we don't look like 'dodgy geezers' or fly-by-nights; we both dress the same; and I do realise that it looks a bit poncy. Now-and-again when we're in 'uniform' and shopping in Tescos, she'll hold my hand, and I'll have to remind her not to, 'cos we're in uniform!
(I don't really care to be honest, but I've got a 'Geordie image' to keep up.)
But more importantly, when you're clean shaven, washed and smartly dressed (even if it is a window cleaner's uniform), it gives you more confidence when you stick a good price in.
You've got a lovely van; it looks the part - but shame about your dress; and should I really be telling you this when you're my competition?
