Allison wore a custom-designed silk satin tea-length dress with ruching at the bustline and a V back with covered buttons. I love shoes, so a short dress was a must to show them off, Allison says. The fabulous footwear: gold peep-toe sling backs with an enamel and pearl flower at the toe. Allison and Mark also rented a vintage city cab to shuttle them to the ceremony. This same cab was used in another urban love story (and one of Allison's favorite movies), When Harry Met Sally.
