There are two different couples that do that. One couple is there for an extended time twice a year and model the suits they have had made by Luis. They walk the entire length of the beach several times a day and are referred to as " Ken and Barbie". They hang out on the Club O Beach and are personally known by many.
Ken and Barbie usually change their suits at least once each day as well. We see them when we're there in November/December.
