It looked similar to this, though in a lovely light grey color. (I neglected to take a before picture of the one I purchased. Sorry.)
I carefully removed the binding around the arm holes and saved them. Using a free pattern I found online, I cut out a little jumper for my daughter. Then I hand sewed the binding back on to the new, smaller, arm holes.
And here's what I ended up with. After my daughter wore it once, I decided it was just a bit too plain, so I found some fabric flowers to jazz it up a little.
Final product! Adorable, and kept her nice & warm!
