A little help fixing a dress

I bought this real pretty knitted long sleeved black chenille trapeze dress and there are places where it looks like a stitch wasn’t finished so that I have a couple of holes that don’t belong. What is the best way to fix it? I am a little worried that if I don’t fix it then I might have an embarrassing problem when I wear it. And it is just so pretty that I don’t want to have to throw it away. Please help me to save my dress.

maybe you can just find a yarn in a matching color and a similar weight and then duplicate stitch (on the back side) over the areas that have the holes. i would start quite a few stitches back and run it quite a few stitches after the holes.
