A Canadian school board has demanded a new “professional” dress code for teachers following months of backlash over a trans teacher with “clownish” giant prosthetic breasts.

Trustees on the Halton District School Board unanimously passed a motion on Jan. 3 ordering the director of education to develop a policy to ensure “appropriate and professional standards of dress and decorum in the classroom,” Fox News reported.

The district’s Director of Education Curtis Ennis will have until March 1 to create the policy.

“The HDSB’s commitment to human rights remains rooted in our core values and commitment to each and every student and staff who identifies as a member of an underserved and underrepresented group, and our approach is informed by opinions from leading employment law firms with human rights and equity advisors,” Ennis said.

“This commitment and approach will continue to be applied as the HDSB looks to fulfill this motion.”

Photos of the Oakville Trafalgar High School teacher, identified as Kayla Lemieux by local media, went viral in September and swiftly garnered global attention.

The snaps, taken by students, show the blond educator wearing tight clothing that emphasizes her gigantic Z-size prosthetic breasts while teaching in the classroom. Huge nipples can also be seen protruding from her fake, balloon-like bust.

The eye-popping photos quickly sparked protests, angry complaints and even several bomb threats at the Oakville school, located about 20 miles outside Toronto.

The school board has continued to stand behind the trans teacher, who began identifying as female last year, according to the Toronto Sun.

“This teacher (who teaches shop) is an extremely effective teacher,” Halton District School Board chair Margo Shuttleworth said previously.
