Personally I have always preferred Peter with Felicia anyways. Nothing against Mary Jane (at least, the proper comics Mary Jane, the movie versions suck to the extreme) but I personally like Black Cat better with him.
More like those fluffy thingies on... what's it called in english? The same place as bracelets would be anyway.
A pity sarcasm can't get through in written words or I would have said something appropriate, because honestly folks one only needed to see Black Cat and Spider-man only ONCE to realize that white thing was part of Black Cat's suit (and nobody figured out I was making a joke...)
