I got my kilt today from USA Kilts & it fits perfectly!

Also purchased the Kilkenny vest & jacket. Have to get the jacket tailored a bit and taken in but my ultimate question is about the button on the jacket.

Is the button on a Kilkenny jacket supposed to be able to button or is the jacket supposed to be open? Most pictures I've seen it is unbuttoned and the jacket is open but there are a few here & there that I have seen it buttoned.

Just trying to figure out if there is a proper way to wear it or is it a matter of preference? Just want to know before I get it taken in.

Thanks,
Matt
