The school where teacher Jeremy Forrest seduced his 15-year-old victim has banned girls from wearing 'figure hugging' clothes or short skirts.
A directive to parents from the school said: "Figure-hugging tight, skinny-fitting styles are not acceptable. Trousers are required to be loose around the ankles without Lycra or similar."
Parents have been told that pupils who break the dress code risk being sent home.
Bishop Bell Church of England School in Eastbourne, East Sussex, wants pupils to have the 'highest standard' of appearance, and banned make-up for girls below school year 10 - ages 14 to 15.
Girls are banned from wearing underwear which is visible or skirts which are more than two inches above the knee - and pupils are not allowed to wear 'figure hugging, tight, skinny-fitting styles'.
However, there is no suggestion the rules were imposed as a result of Forrest's conviction for abduction and sexual activity with a child, which later saw the 31-year-old jailed for five and a half years in June.
A newsletter to all parents said the new guidelines will encourage pupils to 'take pride in their appearance and their school'.
It stated: "We strive for the highest standards in all aspects of school life and believe that pupils should take pride in their appearance and their school.
"High standards of appearance are an important part of each pupil's sense of values and are a preparation for the world outside school.
"Therefore, the school has a clearly stated policy that all pupils are expected to wear full school uniform both whilst journeying to or from school and, of course, on site.
"The highest standards are maintained from the moment pupils enter the school and parents are expected to support the policy with regard to uniform."
The letter includes a pencil portrait of a child with various parts 'tagged' with uniform guidance. It states that girls are not allowed to wear 'coloured or patterned undergarments' under their blouses which are visible.
Nail varnish, body piercings and most items of jewellery were also deemed 'not acceptable'.
Maths teacher Forrest, 31, was jailed for five-and-a-half years for having sex with a 15-year-old pupil at Bishop Bell School in Eastbourne, East Sussex. He had gone on the run with her to France.
