I do think for a wedding,however casual,a bit of an effort is still appropriate.Might I suggest a white shirt,tie(not bow tie),an Argyll jacket and waistcoat(vest) and suitable kilt hose and shoes.You could forego the Argyll,if needs be, and just wear the waistcoat(vest) which is a very effective way of being casual and smart at the same time.
I agree with the above, but I would suggest a plain coloured tie,(four in hand) picking up on one of the colours in your kilt. The waistcoat automatically upgrades the outfit without looking out of place with saxon styles (I am assuming sport coats and ties)
