Sexy Halloween Costumes

I was riding the jeepney on my way home the other night. There were three girls talking about what they will wear on their coming office Halloween party. One thing is common among their wishes, they wanted some sexy Halloween costumes. I was thinking, whatever happened to just cute, fun, or just really scary Halloween costumes. It seems that younger people prefer sexy things on anything. Nothing wrong with it but somehow, I find it overboard sometimes.
