Fr. Bryce has posted about this couple who married in pirate attire. This started a comment box discussion on the decency or otherwise of modern bridal attire.
This reminds me of the quick response of a wily pastor who was confronted with a bride who was showing too much. As she made her way up the aisle he asked his server to get a surplice from the sacristy. When she arrived at the sanctuary he put the surplice over her inadequate dress and gave her a blessing. The congretation took it as being part of the wedding ceremony.
