The white collar looks good to me from 84. Maroon shorts though do make them look like bathers.1984 Manly seem to have had 2 main jerseys with games in maroon and others in white. The maroon jersey had the white collar but i don't think it looked any good. The maroon shorts don't help. In 1985 it was the traditional Manly maroon jersey, same as the 1987 grand final.
This game has the 1984 maroon jersey.
