I would gladly take my vows again just to wear this to the rehearsal dinner! I LOVE the lace detailing on the sleeves, and I love how the zipper in the back POPS. The material is EXTREMELY soft. I highly recommend getting a petticoat with this dress if you are looking for more of the 50's look and want to keep it flared out, but it is not necessary.
(for a more modern look you can wear without petticoat, like the picture. It has less flair in the skirt)
