In this case a slightly grey boy's vest which had done that annoying twisty thing on the seams ... but I decided to make it into a dress.
It was too wide for Poppy so I chopped the sides off and some of the length.
My idea was to sew some tiers of pretty fabric onto it. If you are a child of the 70's you will probably remember an item of clothing which had a nylon vest top and a tartan kilty skirt attached to the bottom. This is the same idea - a skirt attached to a vest, supposed to be worn with a t-shirt over the top.
So it doesn't matter what the vest is like - that bit gets covered up.
I think it has worked quite well as an experiment - I have to admit is rather snug for Poppy and only just fits. I should have allowed more width to get it on and off more easily.
