I think if you are very flat or thin then it would be a good look. Halter tops tend not to look great on people who are busty or more curvy. You never know until you try something on though.
She def. has a larger bust so if you are smaller you could pull it off, but it all depends. I wouldn't say it was skanky, but it's not the image I want to portray on my wedding. Then again I don't want something too virginal either.
In response to Acwinsett, I love that dress!!!!!! I went to a wedding about 4 years ago and the bride had that same dress. I have seen it at David's Bridal and it must be one of their most popular ones. I just love it!!!!!!!!!!!!
