Well I for one think its a major improvement over her previous belly shirt costume and mini skirt that was convieniently was getting smaller and smaller. The 52 costume looks unique.
Look at what Marvel did to Ms.Marvel who is now Captain Marvel with her iconic black and gold costume. Then they change it to the godawful flightsuit. Also Storms costumes have been pretty attrocious as well, except for her black original and the white Astonishing X-Men costumes.
