Thoughts on these dresses for a formal evening wedding?

So I bought a gorgeous Mac Duggal dress (see my last post) but it turned out WAY too sparkly.

I’m wondering about these 3 now.

DC: We’d love for our guests to dress to the nines with us! Our wedding is a formal affair, so think elegant evening wear-suits and ties, floor-length gowns, or your most dapper cocktail attire. Let’s make it a night to remember, filled with love, laughter, and a little old-school glamour!

Questions about the first two: * Is the first one too dressy or too white? * Is the second one too “main character”? I got a few of those remarks when I posted before

And just general thoughts on all three?
