Betazoid wedding

Marriage ceremony conducted unclothed

The traditional wedding of Betazed, at which the couple and all their guests attend naked, and which is often the outcome of a bond arranged in childhood.

A traditional Betazoid wedding is held with everyone present unclothed, bride, groom and guests alike. Many marriages arise from genetic bonding, a pledge made between families when the partners are still children.
The custom is established in Haven, set in 2364. Deanna Troi is called on to honour her bonding to Wyatt Miller, the son of human friends of her late father. The Enterprise crew and the Millers are uneasy about the dress code, and Lwaxana Troi enjoys their discomfort. The wedding is abandoned when Wyatt joins the Tarellian plague ship.
In Cost of Living, Lwaxana brings a stuffy engagement to an end by arriving at her own wedding in the traditional manner. At the close of Star Trek: Nemesis, William Riker and Troi are bound for a second ceremony on Betazed.
