18-year-old Macy Edgerley from Texas was recently sent home from school after her outfit, which consisted of black leggings and a long grey and orange top, was deemed inappropriate by Orangefield High School.
Outraged that her younger sister was subject to punishment as a result of her outfit choice, 21-year-old Erica took to social media to voice her disgust.
Uploading two photos of the offending outfit, Erica outlined her issues in a post which has since gone viral, having been shared over 90,000 times.
In a furious post which campaigned against blatant body-shaming, Erica wrote: "People wonder why women feel insecure about their bodies or what they wear…it's because you're told your clothing is inappropriate when you're completely fully clothed."
Acknowledging that Macy broke school rules because her top did not hang below the fingertips when her hands were held by her sides, Erica drew attention to the possible the motives behind such a strict rule.
Highlighting her main grievance, Erica said: "Girls cannot go to school in comfortable clothes that cover everything because school systems are afraid that hormonal boys won't be able to control their eyes and minds. And that is such a bigger problem than worrying about clothing."
Questioning the logic behind her sister's punishment, Erica finished by saying: "When you send someone home because of inappropriate clothing, you're taking away from their education. So I guess it's more important for boys to not have distractions (even when they're aren't any) than a woman's education. When will people realise how big of an issue this really is?"
Support has flooded in following Erica's post, with many people calling for the school to apologise to Macy, a senior at Orangefield High School.
Deciding to speak out on the controversy,without going into the specifics of Macy's case, Stephen Patterson, superintendent for the Orangefield Independent School District said: "We want to assure our community that Orangefield ISD strives to maintain a positive and successful learning environment for our students free from disruption and distraction, which includes enforcement of our student dress code."
