You might look for patterns online.

Here is one for US Civil War uniforms that looks as if it could easily be modified into a Montrose. In fact, that is what I am planning to do: http://cgi.ebay.com/ws/eBayISAPI.dll...5513&rd=1&rd=1

From the photos, it seems that the only modification necessary would be the length and perhaps the collar. Oh, and the buttons. A Montrose would have fewer.


This one is simlar to a Montrose: http://www.costumes.org/HISTORY/vict...ages/09_45.htm

You can find patterns for Prince Charlies also.

and the same one here: http://www.folkwear.com/152.html

Or a Highland doublet and an argyl, perhaps a bit old fashioned:
