I reckon there's "smart" and there's "correct", which aren't necessarily the same. On the basis that my other half reckons I don't know how to look smart in a regular business suit, and she's always correct, I don't think I should comment other than to say that McMurdo just about always looks SMART, even if he isn't being FORMAL.

I have often found it helpful to look through historial pictures of kilt wearers and it is reassuring to see how much variation they achieve, especially for day wear.

As others have said, 'just enjoy'.

Cheers, Graham.
