So I took him to the fabric store and he picked out some pre-shirred John Deer fabric, in green, his favorite color. I added some pink to make pockets and straps with. We found some Tractor buttons to complete the look.
I finished it up this morning before he was awake, and he is wearing it now.
I had to add pockets to a dress for my boy, he is VERY BOY, so I was surprised that he wanted a dress.
