See, this bugs me. From someone who grew up reading Spider-Man, I know that one of the main themes was that Peter was always short on money. He was always looking for ways to make some extra scratch and not to buy designer clothes but just to survive and help Aunt May. That always bugged me about that animated MTV series where he was always drinking those $5 iced lattes. The real Peter would never be able to afford those kinds of luxuries. Any incarnation of Peter wearing $100-150 shoes and skinny skater jeans (of which I've bought many a pair for my son - they ain't cheap, believe me!) is not Peter Parker.
I understand wanting to make him aesthetically pleasing because that is part of the draw for a film or tv show but one of the things that made people empathize and sympathize with Peter was that he frequently had to go without. He was never a fashionista. His character would have dressed from K-mart or JC Penney and no one would have wanted to emmulate the way he dressed.
