Top Shop Dress: A tad too much??

I hear black and white is all the rage this spring.  But I think bodycon is out.  At least in my opinion, I am so sick of bodycon!  Like the whole Herve Leger bodycon deal, OVER IT.  And the knock offs are even worse. But gah,  I love this dress.

Now I ask is this a tad too much because I am planning on wearing it to a Spring wedding.  I just feel like it may err on the side of inappropriate.  It's too loud. Too tight.

If I can't come up with anything else, then this will just have to do.
