I'm beginning to get a bit worried about shipping time on my new Argyll jacket and waistcoat so thought it would be worth a question to the rabble. This Sunday, I'm attending a 230th anniversary celebration for a Presbyterian church and participating in their Kirkin' of the Tartan procession. We'll be visiting there as we're members of a different church, but the local Scottish society announced the event and invited all those interested in the kilt to attend.

I've corresponded with the church and they welcome my involvement, but clearly stated they don't have any recommended dress code for the event beyond kilts being very welcome.

My issue at this point is that my new jacket and waistcoat were supposed to arrive today, but haven't shown up and I'm always nervous about delivery dates when I don't have a tracking number. That's what I get for trying to save some money with Etsy. The new items are necessary as my old ones were bought during my recovery from Covid and, thankfully, neither the jacket nor the waistcoat will get around my shoulders anymore (but the kilt still fits!).

So, if my delivery doesn't get to me before the event on Sunday, what would you recommend for attire? PC seems completely inappropriate for an event in the morning. I can get a well fitted vest locally, so would vest, shirt, and tie be sufficiently formal? A shirt and tie without vest or jacket seems to be, well, just off when put on top of a kilt for Sunday morning.

Thanks in advance for any input. I suspect there will be all kinds of combinations with at least a few being rather creative, but as a guest I'm trying to be as respectful as possible and, of course, wearing the kilt properly!
