Well, I've taught this age group and I found most girls to be very shy. However, I will admit that I cannot understand why their moms allow some of them to come to school dressed as they are. A lot of my students already had ears pierced (some with other body parts pierced--nose, eyebrows, etc.). And the mode of dress that some wore can only be described as "slutty redneck" (i.e. skin-tight jeans, blouses that expose part of stomach area and others too low cut). But that's today's public school system for you.
Well maybe he was only talking about a minority of them being flirty. But he did also mention the style of dress as you do.
As if those girls' families had nothing to do with it, right?
While I agree with you on the other piercings, pierced ears is nothing new, nor is it a sign of poor parenting or sluttieness. The ears of many girls are pierced while they are still infants. I remember being so jealous of my friends in elementary school who had pierced ears and I was forbidden to have them. That was back in the '60s and I was in Catholic school. The ban on me having them was an Irish vs Italian prejudice my father grew up with.

No, that is a lack of parental involvement and no dress code in the schools, which stems from a lack of parental involvement. A well written and strictly enforced dress code all but eliminates the problem of inappropriate attire.
