Lee turned to Ditko, who developed a visual style Lee found satisfactory.

One of the first things I did was to work up a costume. A vital, visual part of the character. I had to know how he looked ... before I did any breakdowns. For example: A clinging power so he wouldn't have hard shoes or boots, a hidden wrist-shooter versus a web gun and holster, etc. ... But the whole thing was created by Steve on his own... I think I added the business about the webs coming out of his hands.
