Is this dress color "okay" for a wedding

V • Mommy to 2 precious baby boys 💕
Hi ladies,
I'm 7 months pregnant and will be 8 months by the time I go to this wedding. I had a hard time finding something I loved and finally stumbled around this taupe dress. Everyone i showed loves it but I wanted to get others opinions- is it too light? For my wedding my bridesmaids wore light beige, champagne and light pink bc I LOVE light colors at weddings- but again, I am just self conscious bc I am nervous around these ppl who's wedding I have to attend. 
I think it's ok right? I mean.. I am EIGHT months pregnant, it's not easy to find something that fits and looks cute AND is appropriate for a black tie wedding, am I right? Or am I delusional?
