I don't hate the dress necessarily, but I think you have to accessorise it impeccably for it to work...when brides say they want to look like themselves, but just an elevated version....this isn't it.Looks just like it, good find!
But what would possess someone to see that dress and think 'yep, that's my wedding dress!'?
It's so bland, she could at least have had some accessories with it.
If she's self conscious of her skinniness she could've gone for a dress with slight shoulder pads or puff sleeves or a puffed out lower half.
