This company looks like it is soaked and drenched in arty pomo vibes, atmosphere, ideology. These celebrate subversion, look to be 'edgy', to disrupt, to 'queer' and to undermine norms.
So many of the things noted are actually unremarkable in isolation - the artists whose books are on the desk are both well regarded and established, for example, their work doesn't cause that much of a stir. Look up the Chapman brothers Jake & Dinos for similar stuff - lots of art looks at dark, twisted, and unpleasant themes.
But this company seems to have focussed on and gathered all of these various artists, themes, symbols, provocations and edginesses and are using that as their brand. Hence the catwalk in a sea of mud, with bruised, scarred, pierced, bondage-wearing, mouth-breathing models.
Most of the time all of this 'darkness' in culture is a pose and relatively unproblematic, but it also encourages moral equivalence and and that means it's also a fertile ground of opportunities for anyone with darker motives.
