Uniformity - physical presentation

I am very disturbed with the owner of Uniformity that represents our school in the school shop. She has on numerous occasions dressed inappropriately and comments have been made by teachers, school children as well as my own. I do not mean to be rude but as a representative of the school, by association, it is very disserning to see that nothing is being done as I am aware it has been mentioned before. I understand that there is no particular dress code except being professional and smart, however this woman has on many occasions been inappropriately dressed, I won't go into detail as it is quite embarrassing for me. My son has on more than 1 occasion mentioned her as she leaves nothing to the imagination and for teen boys that is not a good role model. The schools involved is Kings, Bedfordview High, Edenvale High school and Baby steps. These headmasters are all aware of these complaints and nothing has been done.
