Every woman needs a full-length evening dress in her repertoire, and I've loved everything about this one from Blue Banana!
My favorite part about this dress is that it brings a beautiful balance between sexy and modest. The plunging neckline gives you some great options for how much you show off the girls, yet the full-length offers forgiveness for getting a bit too sexy up top. The back of the dress is also high enough to skip the sticky bra and go strapless.
To give you an idea on size, I am 5' 4", 115lbs., 32DD, and I have the black version of this dress in a size 6. It is more expensive than I typically spend on a dress ($95 including shipping on Amazon,) but the quality is outstanding. Not to mention it makes me feel really pretty :-)
Blue Banana offers this dress in three colors, and they ship from the UK. My dress arrived in 10 days, so be sure to give yourself a little leeway on arrival time. I really think you're going to love this one!
