That little chain thingy

[MacConnachie]

I'm thinking that I have seen photos or images from paintings in which these "linked buttons" were more-or-less commonly available "options" for the more formal Sherriffmuir and Montrose doublets/jackets. They seemed to bring an additional bit of flash to the doublet-with-jabot-shirt look. Am I in error?

Sorry I missed this thread the first time around!

There's only one name that I've ever heard them referred to, and that's "chatelain" button closures.

More ornate for women's apparel, they're usually just a strand for the men. It's not intended to be an "extender" for over-grown articles necessarily (although I DO suppose that would work quite well), but they're intended to accessorize the buttons, buckles, links and jewelry. It's all one, integrated silver or gold statement.

The chain for a pocket watch is called an "Albert" when worn across the front of a vest. No idea how I know that, bit like knowing that an elephant is the only animal that has four knees. Useless info until someone ask.
