No, so he ended up going as Darth Maul instead which worked pretty well. I just had to buy red and black face paint and a couple of $2.50 lightsabers.
I found a couple of meters of black fabric in an op shop and made the cloak.
He's wearing my pants and my top (which looks like a tunic on him...clever huh), his wellies and some black fabric strips as a belt and around his wrists. I couldn't figure out a better way to make all the strips stay on so I made him stand there while I stitched him into his costume (then I had to unpick him when he got home). I also had to take in the pants and stitch a sort of V neck in the top to make it fit.
The lightsaber is made from two stuck together with black electrical tape and covered in red tissue paper and glue. Luckily it fitted into the car...just. It would have looked pretty funny if I had to stick it on the roof.
I had about 10 minutes left to paint his face so it's a pretty dodgy job, but he was impressed and that's all that matters. He said the party was brilliant and his lightsaber was a hit with all the other kids.
Hope you're all well. xx
