All of my girls are wearing different dresses in different shades of blue. I want the length of each of the dresses to be similar (some ordered long dresses they are going to shorten). I obviously don't want them too short...its not the prom, its my wedding, and it is at a very classy, vintage place. What is the appropriate length? Some say just above the knees, some say no shorter than 2" above (which I feel may be too short) and others have said right at the knee. David's Bridal does not shorten any short dresses which is fantastic, however, alot of my girls are getting their dresses altered elsewhere. Does anyone know what the proper length is for a cocktail reception? I want to give them an exact length so they all look classy, not trashy.
