According to the social learning theory, students always (you should indicate the frequecy here) imitate other's behaviour especially if the models seem glamorous and sexy. When some lady (the lady here is act as a compound noun, so no need to change to plural form) tutors such as Amanda Tann and June Leung, they both (etc is only appeared when more than 3 example is raised) wear skirts, tube tops or low cuts (plural form for more than 1 person) to exhibit their plump bodies and wear (your next segment is being seperated too far, so wear is added) excessively make up like (for instance is a little bit clumsy here) using (too much/ simply omit the word "much"? You can't only use much alone) mascara, eye shadow and rouge, a lot of students will (as right at the beginning of your sentence, you wrote when, so the sentence is only a presupposition, and so you have to use "will" here) imitate their behavior. Eventually, some “belle's classes” are produced. (it seems that there is a lack of linkage between your last sentence and the second last sentence)
