I used this La Femme (16802) outfit for about three hours to my bro's wedding event. It is in near-perfect condition; however, you may wish to find clean the bottom of the dress, as it is somewhat stained. It is a size 4 and was hemmed to be about 55.5 inches long. Offering for less than 40 % of original rate.
$100 OBO
