I know the appointments have to be booked in advance. Logically, Kleinfeld should ask the bride to review a catalog of some of their gowns and select a couple just to clarify what they envision as the style of the dress.
I liked the second dress the redhead tried on. I think with alterations (especially the sleeves) it would have looked great. If she was looking for the 60s vibe, I think a mini like Rachel Welch or Jane Fonda wore would have been good for the venue.
