I dislike a lot of current fashion as it does nothing for square shaped slightly overweight women, but perhaps nothing does? Certainly not crop tops, low slung jeans, oversized everything (when you are slightly oversized, it's quite hard to achieve the oversized look as everything fits just fine...)
On my teenagers though, a lot of this stuff looks great. I love they don't bother bras, look fab in crop tops/vests, wear long swishy skirts with belts and DMs and so on.
I think fashion is being reclaimed by the young after years of everyone's mum and daughter wearing matching skinnies.
