My 2p
I find it very unprofessional to letch over the opposite sex in sportswear in a professional sporting environment. Sports clothing is often tight and revealing but ask you selves how we’d all fell if men were to publically letch over women’s Lycra clad arses and they were to comment on the bulges int the front of our bibs. People would start to feel uncomfortable and demeaned and we should all therefore observe a common courtesy on this front.
Serena is a professional sports women whose just won her 20-odd grand slam with 30 years committment to her sport, that pic didn’t come from a glamour calendar so perhaps you could treat her with the respect she deserves.
