The largest falsehoods you were ever told were from a man in a suit.
You still butthurt about dressing like a bum?
Dunno ... I've heard some real whoppers from women in pantsuits. One in particular ... IYGWIM.
But the point remains. Clothes do NOT make the man. Manners might. Conduct definitely does.
To "all":
If you think dressing "well" (whatever that means) is important, then dress "well". You'll set an example. The way you conduct yourself when dressed "well" will determine what sort of example you're setting.
