Is this dress too white for a wedding guest?

As the title says really. I was hoping to wear it for a nieces weddings next weekend. DH thinks it’s fine, I’m having doubts! I would wear it with black accessories.

It's a lovely dress and it looks good on you.

I would say it doesn't matter what others think, if you're having the slightest doubt about wearing it for a wedding, just get something else. Not worth the niggling worry!
