Is there a double standard for ”bullets” on moobs (man boobs) and ”bullets” on boobs?

The other day I saw a man with a thin jersey top who was on the chunky side but not obese, but large enough to have moobs. There were nipple indents (”bullets”) on the front of his jersey. No one seem to think twice about it, had he been a woman someone would have commented about it, they always seem to around here. Is that a double standard that nipple indents can be visible on men and no comment or notice whatsoever, but let it be a woman some people have something negative to say?
