I think we may be getting a little sidetracked by the dress aspect here, the root of the problem is the fact that these girls have been enticed into a very dangerous & sinister situation that has been ongoing prior to Police intervention in Dec 2008. Since the inception of "Operation Retriever" it transpires the abusers are from a Pakistani background & that is a fact, no amount of mitigation can change that so there is no racial question to answer it is purely crime & punishment.
