I decided dreadlocks made the most sense of the story, and they almost took on a character of their own (they also seem to mysteriously alter their length from picture to picture - oops!)
Delilah was tricky, as I have no idea what Philistine women wore. So I based her outfit on Minoan/Mycenaean women, as they were Sea Peoples like the Philistines.
I did think this might be a problem, as the favoured style amongst Minoan/Mycenaean women was a frontless blouse. While I'm sure Samson would have appreciated that, Sunday School teachers might not...
So I was glad to find this statue with a decently fastened-up dress!
