姐骚的有气质

'姐骚的有气质' could come off awkward for foreigner. The first half ‘姐骚的’ contains crude term, while ‘有气质(yǒu qì zhì)’ means have elegance. A loose translation would be 'big sister naughty yet elegant'. In a broader sense it indicates a confident and outgoing lady, perhaps one comfortable in expressing herself freely with charisma or attractiveness despite unconventional manners, aiming at presenting a contrast image between inside liveliness and outside demeanor.
