Sherri Hill - 11154 - Elegant Evening Dresses
It is super cute and for the price, buy it... I love all of the clothes I have purchased from Allegra K it is just narrowing down the correct US sizing... I ordered a Large and it fits well but actually a little bigger than I expected I probably could have gotten away with a Medium.
