Someone with Fashion sense please.

I'd hesitate to wear a vest without a jacket. It'll look like you stepped away from the bar for a moment and need to get back. It's the look of someone who's currently on the clock.

depending on the weather I would go for a vest as well. I'm thinking more of a sweather vest that compliments the kilts colors.

Hopefully you have hose to match your shirt/sweater and/or your kilt.

Go and have fun but don't show up the Bride
