Here is my dress!! Should i cover the neckline?

Hi everyone. I didnt have a picture of my dress to share with you all do I went back today to take a pic and share with everyone. I absolutely love it. Fits my personality and goes so well with my wedding theme. Question is should I close the plunging v neck, put a sheer piece in, or rock it the way it is? I dont know what to do. I feel like the plunging neck line makes the dress look young and not matronly. Help!
