It is satisfying to have such a well stocked chest of dressing up supplies that a forgotten about 'come as a fairy tale character' day can be easily accommodated. He wanted to be a pirate, so a pirate he was. I don't mean to brag but a prince, knight, elf, Robin Hood, wizard etc etc would have posed no problem either.
The only shop bought item was, fairly obviously I think, the pirate hat. Everything else had been made or commandeered for the purpose. The grey waistcoat was actually Finley's 'Great Escape' costume. Made for him from a cardi by a good friend when he was just 4 and it was his favourite film.
And it is very satisfying when you spot that a bag, made for a very good friend for Christmas, has become her 'bag'.
That's warm all over glowing satisfaction, that is.
