I keep seeing teen girls about in my town wearing super short tight dresses (usually black), sometimes skirt and crop top with lots of flesh on show. The dresses are made out of material similar to leggings. The bit that gets me though is they wear it with trainers! Sports trainers!
It looks horrible in my opinion. Is this a trend? Where did it come from?
Maybe I'm getting old... I'm pretty sure my mum didn't get the trouser skirt combo I used to wear. 
It's just I don't get the "nice" dress paired with trainers. To me it's like wearing heels with jogging pants... not a good look.
