Advice needed

[Cephas]

My advice would be to double check with your cousin. See what the men in the wedding party are wearing and that will give you an idea of how much you need to dress up.

Informal can mean different things to different people. I did a wedding for a couple once where informal meant "no tuxs" and the men were in suits and ties and the bride had on a simpler white dress than the formal wedding gown. The next wedding I officiated at was also "informal" but there there were no jackets or ties to be seen (lots of t-shirts and sandals though).

A white shirt and tartan tie sound like safe choices. If you add a vest to it I don't think you would look too "formal". But then again the joy of a vest or jacket is they can be taken off and left in a car if you think you are overdressed.

I have to confess that I have little idea on the sort of weather you have in October,but I suppose you must be heading into some sort of cooler weather.So,no matter how casual you want to be, keeping cool/warm is a consideration.

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)

I should probably amend some of what I posted. You can wear a waistcoat alone, but it should be the type that has a full back made of the same material as the front. If the waistcoat has a satin or silk back and an adjustable strap, it is meant only for wear under a jacket.

Although it is the bride's big day, she really doesn't have any say in what the person performing the ceremony will wear. As the celebrant/officiant, a degree of greater formality is required. You can take off your jacket and remove your tie after the ceremony if you wish. During the ceremony it is incumbent upon you to uphold the dignity of your office as priest or civil authority. Stick with McMurdo's advice: Either a clerical shirt or a white shirt, black Argyll jacket, and sold colour tie.
