There are buttons on the inside holding the straps in place. I made it this way so I'd have the option to remove them.
Surprise! The bow at the bottom can be tightened to reveal a cute little ruffle!
The buttons on the back were a last minute thing (In fact, it was just before the "photo shoot" and Sweet Pea was wearing it :)) I added the buttons so the straps could be even more versatile and convert into a sash around the waist.
Now, the trick will be trying to figure out how to blow this up into a version for ME! :)
