I found a similarly colored t-shirt dress in her newer big-girl size. It was hard to find the exact shade of pinks but it's close enough I think.
I wanted to keep the ruffle at first, but I didn't think it went well enough with the style of the new garment.
I cut the main design and some extra background out of the original garment in a rough oval and then evened it up. I didn't want too much of the background pink.
I think it turned out pretty well and I hope she enjoys wearing the owl for a little longer.
