Take two large white tea-towels, a bit of lace from an old net curtain, and a length of elastic to make a frilly hat and apron, thus:
Total time taken for project: 1 hour, give or take.
Total cost: Negligible. Everything was taken from stuff lying around the house.
I was going to make an all-black skirt, instead of having her wear a black skirt with a colourful design on it, but I'm too fed up with life (eg, being pregnant) to sew anything else right now. We're not going for 100% historical accuracy with this thing, anyway!
I have to say, I am in love with the hat and may just make one for myself....
