Regulation Doublet on eBay

[OC Richard]

Yep that's cool, you don't see those very often.

That style, which we call nowadays the "regulation doublet", was called in the old days simply "the doublet", and was the most common kilt jacket from the mid-19th century well up into the 1930s, when the then-new "coatee" (which we call the "Prince Charlie") started taking over.

The style of lapel changed over the years. Originally the "doublet" had lapels like an ordinary suit coat of the time, usually, but would sometimes be seen with long formal lapels.

After the Prince Charlie came onto the scene, for whatever reason the makers changed the lapels, so that the Prince Charlie and the Doublet had the same style, low lapels usually made of satin. I've never cared for these latter-day Doublets, but prefer the earlier style.
