I do this every time I make an O+S pattern. I declare that it is my favorite, the best garment I have made, the absolute cutest thing I have sewn.....and here I go again!
The Play Date dress is so retro, pretty but seriously funky with the right fabric. It makes a gorgeous dress but also looks fabulous over leggings and tights with boots AND as my twins wear theirs , over skinny jeans.
I am making a sugary sweet version for my baby at present in the C W , Corner Florist pink, but Small One 6 1/2 has requested a blue one in the same fabric and we will make that a little more sophisticated.
It is a great pattern , do consider hunting for it , soon it will be gone!
