My costume is finally done!! Every single bit of fabric on this thing either used to be something else, or was a scrap from another project.
Dress: Hideous sofa slipcover from Goodwill
Sleeves: Leftover from sewing a corset
Chemise: Playpen cover
Partlet and hair covering: Old sheer curtains
Velvet ribbon at waist: Drawstring from old yoga pants
The only part of the dress that is new are the buttons. So I paid $15 for the whole thing.
For the geeks out there, this is a 1490's Florentine merchant class costume.
