The Warriors, who now boast more than 250 members, are honouring the quirks and quality of suburban sport as they celebrate their 40th anniversary this year.
The story of the underwear originates from the club�s inaugural sponsor, Duncraig Drapery, in 1976.
Then known as the Gulls, best-on-ground in each match was declared �Jock of the Week� and received a pair of jocks donated by the club sponsor.
While it was larrikinism off field, the club took its quest for success seriously.
The side, originally based at Craigie�s Otago Reserve, lost its first match in its maiden season but went undefeated until the grand final when it was beaten by University.
Grand final losses in 1977, �80, �81 and �83 followed before the G Grade side claimed the club�s first premiership in 1985.
It was the beginning of 14 flags for Whitford, which moved to its current home at MacDonald Reserve in 1979 and worked up to a place in the WA Amateur Football League�s A Grade competition.
Club officials are hoping to attract as many past players as possible to an anniversary ball in June.
