The Mona Lisa costume was from a long black dress that I bought at the Salvation Army for $5, and I made the alterations necessaries with more black fabric for it to look like the 16th century and more Mona Lisa like, the frame is cardboard with a gold fabric I had at home. Makeup was really simple.
My boyfriend dressed up like Da Vinci, I used his graduation gown and made some alterations, a knees long brown dress underneath with a brown belt and black leggings. I made his hat, painted his hair with temporary gray hair spray, and bought his beard in a local costume store for $6. Didn’t find a wood painter’s palette so we made one of cardboard, really simple.
