Lol they put trackers in bras to prevent shoplifting or theft, a woman can easily switch out a bra in the dressing room or put it in their bag. Because they are bras you have to be able to try them on without a bulky security tag so they put tracking stickers instead. If they wanted to be nefarious they would have put a tiny hidden tracker in the bras, not an obvious sticker.

are you kidfing me trakers in our bras. hmm i bet that how they got teens. they know where they are.
