SNAG!

So Buddy the Beagle Baby, the angel that he is, got his chops into my cute little baby dress I've been working on.  I thought I'd saved it at the time but just now noticed this snag just as I finished weaving in the yarn ends.  So the dress is finished now except for the trim which is a decorative edge around the bottom, neckline and sleeve edges.  I have pulled the snag through to the inside of the dress and you can't tell anything from the front side now.  It is a double crochet stitch (US) that is snagged but the stitch is fine.  The yarn strands have separated and one is pulled farther out.  This snag is about .5 to .75 of an inch.

Does anyone know the best way to fix something like this?

Other than that the dress is finished now except for the trim and I don't have enough yarn to finish that.  I will either have to get another skein or use a contrasting color.  Or, I have thought about just not adding the trim.  The trim is a simple chain 1, slip stitch in next stitch around which just gives it a small rippled edge which reminds me of a row of garter stitch in knitting.  I tried to get some pictures but I didn't have anyone to hold it for me and I don't want to put it on a hanger again because I'm worried about the straps getting stretched out from the weight of the skirt.  I still have to get some ribbon to strengthen them.

So here is a picture of the top as it is now. The trim would go around the neckline and edges of the straps and underarm and also bottom of the skirt.  I do have 2 skeins of this Caron Simply soft Party with a metallic purple thread in it.  You can see a strand of it over the dress.  What do you think?

Should I....

1. Use the contrasting color
2. Get another skein of the same yarn or
3. Skip trim all together

Here is a picture with the whole ball of yarn.  It looks a little more blue than it is.  It is more of a plum color.  What you can't see in this picture is where the light hits the metallic thread it has a hot-pinkish purple shine to it.

Below is a picture of the skirt portion of the dress.  It was a hard shot to get since I had to hold it with one hand and take the picture with the other.  It doesn't lay flat very well.

P.s. Buddy says "I'm the baby, gotta love me!"

Okay, here is another picture where I added the edging to the top but I didn't weave in the ends so I can undo it if I want. I'm a bit of a chicken liver and can't quite commit to the darker edging yet.
