This was an experimental design, I had to get it out of my head to see how the top worked.
The basic design is a square but the cinch top makes it look more like a triangle. The top has slashes to feed the Kimono Belt threw to be used as straps and to close the bag. You can wear the strap as two shoulder straps or let the bag sit low and have it cross body.
This purse is made from a reclaimed black leather jacket and a Silk Kimono I found on sale in college and stashed away.
