The banyan was made to be worn both sides - red and green. Sadly he doesn't like either side :-DD
Fabric: Faux silk (green) and faux wool damask (wool-poly-blend)
Pattern: Leloir's pattern for Robe de Chambre with some ghanges..
Year: about 1730's
Notions: Red and green thread
How historically accurate is it? The banyan pattern is correct, and the cap - though my own pattern - could be so correct too. Fabrics are not accurate (yet they look ok), and I used a sewing machine the whole time.
Hours to complete: One day
First worn: just for the photo shoot and perhaps never again. He just felt very stupid wearing the outfit :-DD
Total cost: I bought the green fabric for 15 €, the rest is from my stash
