Rosettes...are styles period specific?

[OC Richard]

I find it interesting that some of the Scottish regiments use bows on their kilts while some use rosettes proper (a full circle of ribbon with a covered button in the centre).

Here's the bow-shaped things which the regiment itself calls "rosettes" on a Black Watch regimental kilt, and being worn by the new Royal Regiment of Scotland (which has replaced all of the old Scottish regiments)





and here's what I think of as "rosettes proper" being worn by the Pipe Major of the Royal Highland Fusiliers...it's not "artistic licence" because I also have a large clear photo of this regiment's PM which clearly shows the cloth-covered buttons at the centre of these rosettes.
