They may have the right to do a cursory search for weapons, but it is my understanding that when a female is taken into custody any thorough searches are done by a female officer. I didn't say that she exposed anything, but it seems to me that she would have had to lift her shirt to do the thing with her bra.

In my opinion, regardless of the standard procedure with adult females taken into custody, any search of a minor, with the exclusion of a cursory search for weapons, should only be allowed in the presence of a parent or legal guardian.
