The original question asked "proper hose with the PC".

I've not come across any 19th century images of the PC but it shows up in the Highland Dress catalogues from the 1920s and 1930s I have.

This is how the Prince Charlie (sometimes simply called "coatee") is shown:





The Prince Charlie is NEVER shown with selfcoloured/plain hose, but invariably with diced or tartan hose and buckled shoes. (The shoes shown are Mary Jane style, "Cromwell" style, or ghillies with buckles at the toes.)

My 1936 Paisley catalogue states "The Prince Charlie Coatee is correct dress for gentlemen's evening wear. The coatee is of black superfine cloth finished with silverplated buttons." Shown are black PCs with wingcollar shirts, black bow ties, full tartan hose, and "cromwell" buckled shoes.

My 1936 Anderson catalogue is interesting as it shows a green Prince Charlie coatee worn with lace jabot, tartan waistcoat, diced castellated hose, and "cromwell" buckled brogues: a much more formal concept of the PC than we have today.

It states "The coatee is specially suitable for a young man or an older man of slim figure. It is definately less suitable for the stouter figure. A neat close-fitting coat, it is generally made in black cloth with silk facings or in green cloth... the waistcoat may be of cloth to match the coat, tartan to match the kilt, scarlet or other colour...
Stockings... are knitted to match the tartan of the kilt, or diced stockings of different colours are correct."

So say the Highland Dress makers of the 1930s.
