I can't tell from this report if the two girls were kicked out of school permanently or were suspended temporarily for wearing bikinis and having their bodies painted in school colors for Homecoming.
There's a time and a place for painting your body in school colors and showing off--and school isn't that place. Had they dressed this way at the football game itself, the situation would be a bit murkier.
I didn't inhabit that gray area when I was in high school. A friend and I painted ourselves in school colors from our waists up, went to a football game, and cheered with the cheerleaders--and being shirtless, we showed all of our cleavage! And we thought it was great, too, until the principal chewed us out on Monday morning. I have a picture in my senior yearbook, but I think my yearbooks are in the garage.
But let's be realistic, girls--bikini tops are not appropriate at school. You know that. School spirit is great, but it doesn't override the fact that bikinis aren't appropriate attire at school.
