This is one of the dresses from the H&M Bohemian Deluxe Collection featuring Giselle Bundchen. You can see it on her in the ad campaign.
I featured it on my site last week. I got a few pieces from this collection that I personally like and would recommend. I think I tried on just about every piece (haha).
I’m predicting this dress will be a hit amongst bloggers.
