I loved this album of a wedding inspired by The Little Mermaid, posted by the Disney Weddings blog. Look at the shell-styled macarons!
I particularly liked the table covers, which look to me to be evocative of the ocean floor – deep blue table covers to start with, layered over by shiny sheets (recalling the white waves and the sandy bottom) covered over with what look like little crystals (possibly small plastic chips? maybe recreating a lens effect?).
