It took me about five weeks but that was mostly because my sewing machine is at a friend's house since I have no space right now. I was driving 45+ minutes up to Maryland every few nights to sew for a couple of hours during the week and spent a few weekends fitting this in between D*C costumes. It was a bit of a nightmare.
I have no idea if I'll bring it to D*C or not. I don't particularly like the costume because of the stress it's caused me.
