Sparkely shirt make-over

This child of mine loves sparkly things. When I saw this shirt hanging in the thrift store, I knew I had to do something with it for her. Perhaps you can see that it's really too wide and the neck is too big.

I sewed a seam right up the sides of the shirt, eliminating about 2 inches of fabric on both sides and half of the arm opening.

Then I cut the excess fabric off.


So now it's much more fitting, but I still don't know how to make the neck smaller. Any suggestions?

In any case, it's cute with a turtle neck underneath :-)
