Another pattern from Ravelry. This one is called 'Robe d'Ete' (summer dress).
The pattern comes in two sizes - for ages 2 and 4. However, there are no measurements or gauge so the first dress was a bit more of a miss than a hit. I made the size 2 in pink cotton but it was just a bit too tight across the back.
So this is the size 4 one, in green cotton. The fabric for the dress is from a pyjamas bottoms that I bought in the charity shop for 1 euro.
Of course, this dress is too big! I don't think it'll be too long 'til she grows into it though.
