15th century doublet
These are some of my inspiration images. I opted for front lacing as in the first, with the hose tied to it at Guillaume's waistline and a longer hem than the ones on the young lads in the pictures. 122 eyelets in all. I think I could do fewer than 36 for the hose though. The overgarment ("giornea") needs a bit more length at CF & CB to balance the bias stretch of the semicircular cut and the angle of the neck opening.
