I don't know how this topic got past me in View unread posts list but it did.
A few suggestions:
Cotton/Linen/Silk Drawers under your Trousers
-do- under your Shirt
Heavier weight Linen Shirt than you wear during the Summer
Guernsey Frock (Sweater)
Wool Waistecoat instead of a Linen Waistecoat or a heavier weight Wool than you wear in the Summer
Wool Frock Coat if you wear Linen in the Summer or a heavier weight Wool than you wear in the Summer
Wool Greatcoat (A blanket coat would do if cut from a Greatcoat pattern) A Northern Capote would be a bit out of place IMHO. BTW Capote is French for Overcoat however my translator doesn't go from Overcoat to Capote. Go Figure. We have over the years come to believe that a Capote is particular design when in reality it is just an Overcoat.
You may want to slant your styling of your clothing to the Spanish side of things but, I wouldn't go overboard with what we see in modern Spanish influences e.g. concho rounds everywhere.
Hope this has been of some help.
