question about dress

My son is making his Bar Mitzvah in September my boys are both wearing black suits with blue shirts, my DH is also wearing a black suit with a blue shirt all the color blue shirts are different. Now my question is what color dress should I wear I thought blue also not a dark blue but lighter blue. Any help would be great. Its early September if that matters the 12th I have dark brown hair and green/blue eyes if that helps also. Thanks for any advice

Re: question about dress

I might avoid blue entirely, or just have some blue parts to the dress but not have that be the predominant color - so it doesn't look too matchy with the guys.

Re: question about dress

I would wear a silver or dark grey dress. I would stay away from blue, because it will look to matchy, unless that is what you're going for.
