When we tell a young woman to cover her shoulders, ensure her bra straps are not showing, or send her home from school because the hem on her skirt is too high, we're "slut-shaming" her and reinforcing a rape culture that places blame on victims for "asking for it".
This is the message high schoolers across the US have been trying to get across to their teachers and principals this year, in response to school dress codes that decree some girls' wardrobe choices to be "distracting" to male pupils.
We don't hear a lot about school dress code "violations" here in New Zealand, save for the odd teenage boy who refuses to shave his face. Though when I think back to my school days, girls were often sent home if their kilt hems rose above their knees (uniform regulations specified girls' hems must fall between their knees and ankles).
School administrators argued this was for "modesty" reasons, but as the examples singled out in the US this year explain, by enforcing a dress code onto a young girl, we're telling her that hiding her body is more important than her education.
Slut-shaming is the act of making a female feel guilty and inferior for behaving in a way others deem to be sexually inappropriate. It could be for violating a dress code by dressing "provocatively", as the above example explains. It could be for making a woman feel "wrong" about casual sex, frequent sexual partners, or even just for vocalising the fact she enjoys sex. Or, it could be what the entire world did to Miley Cyrus in 2013 when she performed We Can't Stop/Blurred Lines with Robin Thicke at the VMAs.
