I just bought my dress yesterday (yay!) and have been looking at a necklace I love for awhile. But now I'm not sure if the necklace will work with the dress, so I'm looking for opinions

Here's the dress..
And the necklace..
It's about 16" long so it's short enough, but I think it might be a little much. All input is appreciated, thanks!!
