The Blogger's Dilemma

I bought this dress at the end of spring, thinking I would get plenty of use out of it during the summer.  Wrong.  It still has the tags on it.  I put it on a lot, but then decide it isn't quite right for whatever the occasion is.

Now the question is, is it appropriate to wear to a wedding?  I've seen several girls this summer (including a mother of the groom?!) wearing white patterned dresses to weddings.  What do you think, so good or no good?  Would you ever wear a white patterned dress to a wedding?
