Well, these TV series are created and mostly written द्वारा Darren तारा, स्टार and Michael Patrick King, also they are based on book द्वारा Candace Bushnell (which I haven't read yet), at the moment I can't remember who is a designer of requisites and whole scene looks, आप can try to खोजिए in internet या read ending credits carefully. Hope I helped a bit. 🙂
