Costume design.
Costume designer Lindy Hemming explained that Bane uses a mask to inhale an analgesic gas, which, in director Christopher Nolan's words, "keeps his pain just below the threshold so he can function."
In designing Bane's costume, Hemming needed it to look "like an amalgam of all sorts of bits and pieces he cobbled together, as he passed through some very remote places.
We made parts of his vest, for example, from fragments of an old military tent.
His clothes are militaristic, but are not in any way a uniform."
Hemming also designed Bane's mask to look "animalistic".
Costume effects supervisor Graham Churchyard created a three-dimensional model of actor Tom Hardy's face and skull to design the mask, allowing the mask to perfectly conform to the contours of Hardy's face.
Hemming personally designed Bane's coat, which she admitted took two years to complete.
Taking inspiration from a Swedish army jacket and a frock coat from the French Revolution, it was designed to make Bane look like equal parts dictatorial and revolutionary.
The design was difficult as Hemming struggled to find a tailor in Los Angeles who could work with shearling.
The Batsuit consisted of 110 separate pieces, each of which had to be replicated dozens of times over the course of the production.
The base layer was made of a polyester mesh that is utilized by the military and high-tech sports manufacturers because of its breathability and moisture-wicking properties.
Molded pieces of flexible urethane were then attached to the mesh, to form the overall body armor plating.
Carbon fiber panels were placed inside the sections on the legs, chest and abdomen.
