Jock and Sandy are absolutely spot on. Highland morning dress consists of the following:

Kilt, kilt pin (not a blanket pin type), silver-mounted sporran (fur, seal skin, or leather), silver sporran chain, tartan hose, silk flashes, black, silver-mounted jewelled sgian dubh, dress brogues (buckle and strap) or plain brogues in fine leather (not ghillie brogues), black barathea (or vicuna) jacket and waistcoat (five buttons) with silver buttons, white shirt, grey silk tie, bonnet with crest badge.

While silver buttons are de rigueur, as are gauntlet cuffs, plain cuffs and self-covered buttons (as on ordinary morning coats) are acceptable.
