Warmer weather is here, which means so are horror stories about schools sending teen girls home for daring to reveal a bra strap, bare midriff, or shoulders. But some Ontario teens are fighting back. schoolgirl r @rachel_venneri #croptopday #standinsolidarity 11:58 AM - 26 May 2015 Reply Retweet Favorite Today is #CropTopDay, a movement started by a Toronto high school student named Alexi Halket.In an event page on Facebook, Halket wrote that a male teacher at Etobicoke School of the Arts complained that a shirt she was wearing one day looked "too much like a sports bra." "I went in to the office and refused to change or cover up, and I was sent to the principal where we talked for over an hour and came to no conclusion except a threat that if I wore something like this again I would be called in to the office," she wrote. In response, Halket declared Tuesday — her birthday — crop top day. Courtesy of Kyrstyn Kumor "So PLEASE wear a crop top, sports bra, bralette, bandeau, or anything similar and stand in solidarity against the sexualization of women's bodies on my birthday," she wrote on Facebook. And her fellow students responded. Both girls and guys showed up to school proudly wearing crop tops, some with messages of solidarity written on their skin.

But #CropTopDay has now taken on a life of its own, spreading to other schools and gaining support on Twitter from people outside of Toronto. dora @lussowo I got uniform but I'm still supporting #croptopday (sorry if my shoulders are too distracting) #Standinsolidarity 01:40 PM - 26 May 2015 Reply Retweet Favorite ☽Pauline Styles☾ @pauline326 @Currently1D #croptopday bc as a woman I should be able to feel comfortable and confident without being called out 10:48 AM - 26 May 2015 Reply Retweet Favorite Crop tops aren't the only clothing item that's been targeted by schools — girls have gotten in trouble for wearing halter tops, leggings, spaghetti straps or just a hint of a bandeau.
