Check out the comments from Anthony Russo below about the Spider-Man costume.
"It is a new costume We were trying to pull forward the work that we had done in Captain America: The Winter Soldier on Cap. So, the innovations that we made to his costume in that form are very much the tonal texture that we are pulling forward. Civil War is very much connected and rooted in The Winter Soldier. So, as far as the specifics of the costume, we don't want to give too much away, but it is a new costume slightly different from what you've seen before. And it's grounded in that Winter Soldier tone."Movieweb has the full story below.
