It's like a onesie for adults.
I bought this from the lovely Isla at A Fine Day for Sailing. And then I found out she has a gorgeous blog by the same name. I highly recommend it.
The romper is a bit large, so I cinched it with a belt at the waist and called it a day. My favorite part? The gingham trim.
