Girls, is wearing a normal looking lacey bra (and nothing else above the waist) in a public area OK for a minor?

Would just like girl's opinions on a rather odd occurance this afternoon, whilst i was driving to a shopping centre underground carpark.

Before i turned off and drove down underground, i noticed 4 girls no older than about 16 in normal (not bikini looking at all) looking bras and shorts and short skirts joyfully bounding across a street crossing. All they wore above the waist were normal lace bras of various designs. It was very obvious they were bras and not bikini tops.

The temperature was searing hot today which is likely the reason they were dressed as such.

I just thought it was rather odd, but i prefer not to judge people by how they dress.

So i ask you, what are your opinions on this?
