The karaoke-bar I work at has themes every night, and our upcoming theme was skulls. Not owning anything with skulls, I scoured local thrift stores and the *only* thing I found was a 3X t-shirt that I was absolutely swimming in. So I pulled out my sewing machine and turned it into a dress.
I have to say, to do it over again, I would have it hug my curves more, rather than being so boxy, but I'm still learning. :-D
