In my Newton's Radio I mention some alternative fashions,
Due to Joffrism (an alternative Darwinism) getting mixed up with nonconformist churches a strong movement for Truth in clothing arose, add in a revival of celts, Americans (OTL indians) and other noble savage sort of clothing and we get: Respectable religious nudism, banned cosmetics, Kilts, beech clouts
And naturally in time the reaction of the young (in this time line called the Fey Folk): Obvious cosmetics, high heels elaborate clothing, padded codpieces and bras etc.
