eh i think its more of a coincidence cuz if you look at the rest of ralph's collection, purple label and polo, the only things that coincide are the 'American Roughwear.' Dsquared seems to have cranked out the same stuff since 2002.
when i see ralph's collections i think 'oh these must've been influenced by oxford baggies and exaggerated pleated back jackets from the 20's' or 'those look influenced by sacque suits' or 'he's trying to recreate that southwestern ranch estate look' or 'here comes that ivy league prep look once again'
when i see dsquared its more like 'oh its the dirty, sl*tty, but rich, trucker look, again.' or 'oh no wait, its the sl*tty woodsmen' or 'its a pair jeans that have a boxer brief fly and hang so low the models *** is hanging out of it'
