The Varieties of Traditional Experience: To Jabot or not To Jabot

[MacMillan of Rathdown]

Also, what about a white bow tie instead of a jabot for white tie formal? Is it done and, if so, with what jacket/waistcoat?

A white bow tie and (usually) white waistcoat will transform any open coatee or doublet (Prince Charile, Regulation Doublet, etc.) into white tie attire. Strictly speaking, with civilian attire, a black waistcoat should not be worn with white tie. While tartan and coloured waistcoats may be worn with black tie, the safer option is to stick with the white waistcoat when the invitation stipulates "White tie, Highland attire preferred".
