I actually disagree - I can't really imagine a bride wearing a short, polka dot dress. Plus, if you wear it with a cardigan or wrap, it definitely won't look bridal at all. I think it would actually be a great dress for a wedding.
I agree with gingembre1...with the right wrap it would be perfect. I would wear something summer-y colored instead of just black, like turquoise. Another statement color would be great because the colors of the dress are so neutral. I love anything turqiouse or coral for summer weddings...just my opinion
