Speaking as someone who is TG, I don't understand the reasoning behind the decision here at all.
RAF women banned from wearing skirts on parade | News | The Times & The Sunday Times
The Royal Air Force has banned women from wearing skirts on parade and issued a trousers-only rule in an attempt to become more inclusive. The move is partly owing to an increase in transgender troops and was discussed at a meeting by officials who address issues such as diversity, inclusion and uniform policy.
It is believed to have been put into action last year as part of a regular review of uniform policy. No decision is believed to have been made on whether to continue with the ban. The rule change has been criticised by some servicemen and politicians. Philip Davies, the Conservative MP, said: “It’s a ludicrous decision.”
The RAF first allowed women to wear trousers on parade in 2001. Some 14 per cent of the RAF’s 33,000 personnel are women, a higher percentage than in the Royal Navy or Army.
