Chill guys. ANY female has the right to dress as she pleases, so long as PRIVATE parts, determined by CIVILISATION are covered, reason being breast & nipples are WHAT we Humans had been fed with, & the vagina being WHAT we-male & females-came from, parts which WE should respect & honor.
She did NOTHING wrong with her dressing. It's her choice and Earth born free will, due to myriad of reasons - perhaps a hot day, causal wear, to attract males she wants, etc.
The day when we restrict others to show off assets properly covered is the day when we restrict Humanity to beauty of the DIVENELY created Human form, to be appreciated & ESPECIALLY to be respected, come to NO harm by those whom FAILED to maintain the form, be envious, or worse- resort to basic ANIMAL & barbaric instincts, of which we descended from un-evolved ancient ancestors from the jungles & caves.
