I've never had any problems with Prada or Prada owned brands, but I would agree that, in general, the price of Prada clothing is incommensurate with its quality. I find that while Hugo Boss suits are pretty good value, their sportswear often leaves much to be desired. The materials are mediocre, the styling is mediocre at best, and the fit is awkward. The clothing seems to have been designed with the balding, out-of-shape, middle managers from Tulsa on a weekend hiatus look in mind. Not good. I'd extend the same criticism to Zegna Sport and Brooks Brothers. To be fair, I don't think that I fall into their target demographic in any case. but in the same price range and and for roughly the same style, I would recommend Cerruti 1881 as an alternative. I actually think that Polo stuff is pretty good value, but I am not a big fan of the preppy look, so I don't own any pieces.
