I used McCalls pattern 9590 from 1968.
The fabric is Sherbet Pips by Moda. It's a sweet bunch of girls on swings.
Miraculously, I installed a zipper.
We tested it out at a holiday party last weekend with a pair of bloomers and pink tights.
V didn't stay clean/unwrinkled for long.
Which is exactly how a three year old should look post-party I suppose.
