It's a summer wedding outside, so I'm not really worried about the style. I'm wondering if it's too white..
This is not the same dress but the closest I could find. Mine is white and a nice brown and there is a little less space between the pattern. The belt is also brown and there is about a 2-inch brown hem on the bottom.
I think that's lovely for an outdoor summer wedding. And no, I don't think it's too white, not with a pattern similar to that. Should be fine. Besides, everyone will mostly be focused on the bride and groom, not what the guests chose to wear. :) Have fun!
I think it's a good choice for a summer wedding. I especially like the cut of the dress. And no, it's not too white. The only thing I'm not so sure about is the white/brown combo. It sounds a bit too bland/casual for a wedding so you should definitely glam it up with the accessories and makeup!
