Collar question

[Jonn]

I'd say out... Looks more casual than smart. Depends on the occasion I guess :-)

I tend to wear Oxford shirts so I wear it inside the jumper collar.

It depends on the collar, obviously if it's a loose fabric one that's gonna curl or stick out then keep it in but generally with a stiff collared shirt you'd have it outside

Exactly this. The collar can look good on the outside if it's the proper kind!
