Hi Longway,

Abroad is everywhere. I live in the UK and for me abroad could be the US (where there are lots of kilt shops). From the US, abroad could be the UK (of which Scotland is a part). You see the problem we have? You need to be a little bit more specific, otherwise the advice will be too general to be of any use to you.

As a general rule of thumb - any jacket that was designed to be part of a suit (with trousers) will be too long in the body and look silly.

Waistcoat (three button) - OK.
Waistcoat (five button) - OK, but not really for black tie.
Cummerbund, instead of waistcoat - people do it, but it only works with a jacket.
Tie, self tied bow tie - OK, really the only acceptable for black tie.
Tie, pre-tied bow tie - Learn to tie one.
Suit Jacket, single breasted - Not OK, too long in the body, no cutaway for sporran, looks silly.
Suit Jacket, double breasted - Only a madman would wear this with a kilt.

If you can get hold of a second dinner jacket (you don't want to ruin the suit), a reasonable tailor should be able to take up the jacket and make a cutaway at the front in a couple of days.

Sorry if this sounds negative.

Regards

Chas
