Sure Nerr.
From the DM in 2009, the same year the DNA tests results were leaked to the global media, see photos of Caster with the other school children, a boy and a girl, in a boys schools uniform and consider whether a girl would be permitted to wear the school uniform provided for boys at a strict Catholic school in Limpopo.
'She wouldn't wear dresses and sounds like a man on the phone': Caster Semenya's father on his sex-riddle daughter

Also notice the article name Semenya as a man and also as a 'girl' throughout the article.
"The name of this unusual student? Step forward Caster Semenya, 18-year-old from an impoverished black township who is at the centre of a row raging across the world following allegations that she is, in fact, a man."
From parts of the article you could think that Semenya have been, what we now call, a gender non confirming girl. If we didn't have DNA test results (that have since disappeared from the internet) we could be less to believe that. I'm not convinced that a girl from a strict Catholic school in rural South Africa, where girls are still to this day at a disadvantage, would be allowed to wear trousers just because she wanted to.
(I've lived in SA and worked in education and see no evidence of schools like Caster's being anywhere near as accommodating and relaxed as has been claimed.)
