A sole trusted garment usually worn by a man coming to the end of his social lifecycle.
When a male believes himself to be in his
prime he will either carefully or indiscriminately choose from a wide variety of garments for the wide variety of social occasions his youth and social status offers. At this point in his life the male subjectively believes all such garments 'looks good on him'. As the male ages he naturally becomes subjectively and objectively less 'in his
prime' and studies have shown that there is a negative correlation between the 'distance from
prime', the number of social events available for attendance, and the number of garments trusted to grace these occasions. When a male declines to the point they have
next to no social interactions, the number of shirts that are subjectively ok for going out dwindles to just one. Please note at this point the suitability of the shirt is purely subjective, as there is also a correlation between distance from
prime and
fashion blindness. Objectively the shirt may be hideous or simply be fashion from the
wrong decade. Once a male is down to one shirt he can
never go back up to
two or more, the shirt is the shirt and although it may be replaced (depending on how
long the male tries to string it out), there is only ever one at this point. At this juncture the man can objectively be described as wearing 'his going out shirt" (singular).
