An Oxford academic has accused women of dressing up as "cowards" at the university.
Dr Peter Morris also said that "women should not wear tight dresses if they have stomachs."
And, recalling the prime minister's controversial claim, Muslim women serving as a paper face or "bank robbers", he wrote: "Boris was right."
Dr Morris, a former lecturer in statistics at St Hilda's College and now an IT consultant, later removed the jobs, the Oxford student newspaper reported. He also appears to have deleted his Facebook account.
An insider in Oxford said: "It is a shocking case when women are justified and told how they should appear to men. It is wrong. You think anyone with this intelligence would make sense to keep such offensive opinions to themselves. "
Students called Dr Morris's comments "sexist and inappropriate". One said, "You want to teach, not the lesson."
Dr Morris made the comments on Twitter in a discussion with an Oxford researcher about the lack of tradition in black tie events.
He wrote: "It seems that nowadays people have no idea what it means – men turned into salons, women came out dressed as Nazis. Yes, I'm old. "
He also described transgender people as "gendered snowflakes".

He said Dr Morris "is not a university at Oxford or an academic college" and added that he now "provides computer programming training with the IT services department within two to three days".
