Whatever you do, Do Not wear any suit, tux, or sport jacket with a kilt. The look is totally wrong.

The reason the kilt jackets in all their permutations are shorter, is two-fold. First, the jacket hem needs to be no lower than the fell (stitched part of the peats). Second, there needs to be an open space for the sporran.

The "bumfreezer" jackets, Eton, Ike, Military Mess Jackets, all look good, for that reason, they come either just to the waist (real, not trousers) or just below it.

A black Argyle with silver buttons and a vest, or a Bramer (Argyle with PC cuffs) in black with silver buttons and vest are very good equivalents for a Tux
