> I haven't followed Spider-Man closely in years, but picked-up the first issue of "One More Day" (couldn't avoid the hype). One question: When did Peter stop wearing the black costume, and why?
Huh. Though I haven't read it, apparently in the issue you speak of, because he hadn't put it on since going back to black.
Also, MJ never saw Spidey wear the costume during Back in Black, and in one more day, you can see him with MJ before he swings off in the red and blues.
Also, I think Peter is looking for help, rather than looking for a fight, so the red and blues might be the better option when visiting dr. Strange. So he seems more familiar/friendly, and not menacing or evil like the black costume.
