It's functioning as a jumper right now in chilly weather, with a collared onesie underneath and tights. Hopefully she will wear it like a top with bloomers in warm weather. If this works, I will be so pleased at this stylish way to stretch a baby wardrobe.
I used this 1970s pattern, making the top a little longer and adding rick-rack trimmed ruffles to the bloomers, but those were the only modifications.
Phoebe and Grandpa. Melt my heart.
