oh my goodness! That is gorgeous! I'm glad your package arrived! As far as your concerns go: It does look a bit shiny... it could be the flash, but if you say it's shiny it probably is. You do look gorgeous in it, but if it's not right for you,
you might try selling it on weddingbee, recycled bride, and sites like that. I've been seeing replicas sold on those sites.
If I were you and if you have time, I would first try contacting dressily. I think you have just a few days and if it is their mistake, they say they will fix it. If they do not, contact the person who runs their facebook page. I saw him help a
person out on there that didn't receive the help they needed after their dress arrived from the cus service team.
If you still don't get anywhere, then I'd just sell it on weddingbee. It might grow on you. I know it isn't what you were expecting (which is devastating when we're brides!) but it really is beautiful on you.
