Unbuttoned Denim is actually a trend?

Teyana Taylor on the Premiere of Kanye short film Runway last week, so she rocked a  black bustier top with a studded motorcycle jacket, heavy chains, and a touch of denim. Her ripped and shredded jeans were slung as low as possible to reveal as much as possible And left it unbuttoned...and all of a sudden, its a trend!..Really guys? Ummh..would you rock the unbuttoned trend. I thought maybe it was a wardrobe 'malfunction' but 3 fashonistas beside me are precise it was a 'Fashion statement'
I'm pretty sure i can let this one pass, but what i did love was 

The heavy gold Chains, Gosh who wouldnt! Hello Mr.T!
And of course the Black Suede Lace up peep toe booties
