The point that actual schoolgirls would quite possibly Google this, or schoolgirl xyz other clothes, and get confronted with all this is another point.
The answer to that is that all children must be magically protected by their parents and even though we know lots aren't and etc, well whatever just doesn't wash.
This goes beyond this garment of course. But in general. I think it would be useful if the main search engines bunged in some algorithms to say, only bring up the X rated stuff if the person is actually putting relevant terms in.
That could be done. If course it would be seen as out of line because.... Reasons.
I got a new phone and tried to search hamster for DD on a crowded tube. Mis-spelt it. So it gave me what popularity thought I wanted. Erm that was embarrassing to say the least 
My point is. That mis-spelling hamster should not bring up porn unless the word porn or sex or fucking or whatever is there as well.
This retailer should not call a backless pair of pants schoolgirl knickers. Because a. It's grim and b. Girls starting secondary school might end up confronted with that in an innocent search.
Yes the internet is mostly used for porn.
But it's ubiquitous. And there are ways of making it just a little bit less grim.
Sorry. Long.
