The Men of Bree were brown-haired, broad, and rather short, cheerful and independent
Brown-haired? Dark brown, but yes.
Bree-folk are also familiar with Hobbits, Dwarves, Elves, and the Rangers of the North, so they seem like a good choice for inclusion in a forum like this.
For the soft kit, I'm drawing most of my information from this quote from Tolkien's Letter No. 211:
I do not know the detail of clothing. I visualize with great clarity and detail scenery and ‘natural’ objects, but not artefacts. Pauline Baynes drew her inspiration for F. Giles largely from mediaeval MS. drawings – except for the knights (who are a bit ‘King-Arthurish’)† the style seems to fit well enough. Except that males, especially in northern parts such as the Shire, would wear breeches, whether hidden by a cloak or long mantle, or merely accompanied by a tunic.
This is the result:
I need to make some linen boxers to wear under the breeches and either some leather legging or boots so I don't bring home half the forest in my stockings, but that's the style I'll be sticking with.
Where I'm running into trouble is with the hard kit. I've looked through the chapters that are set in Bree, but there is just not a lot of information there. Since there is trade between Bree and the Shire, I may pull from some of the references to Hobbit material culture to fill in some of the gaps, but I was wondering if there were any other places I should think about looking.
