Looking Good, Feeling Great - Wedding Attire

I posted this in the 20's forum but I'm just fishing for as many opinions as I can get so I'm copying and pasting my original post here too...


I have a wedding to go to June 7th, I really don't know what the dress code is but I think it's a little more on the casual side? I will have to check on that with my date. But what about this dress? Does the color block make it too casual? It is a rayon/spandex blend if that matters and I'm currently a size 12/14....

I think it is fine for a summer wedding.I would wear a dressier shoe, though.

I think it's fine for a casual, getting married in the backyard or a park, kind of wedding but I think the color block makes it too casual for anything where the reception will be held indoors or is a sitdown function.

It's a really cute dress, though, and I'd be pretty tempted to buy it anyway and find a place to where it.
