How is film costume prepared to withstand heat, movement and action?

In film, costume is one more lead character.

And behind every garment there is technical work designed so it can keep up with the pace of a shoot: long days, action scenes, changes in temperature or difficult weather.

In this video, Paco García Galipienso explains (in Spanish) how the costume department uses different techniques and materials so that clothes work when the demands of the shoot require it.

Because what looks like an ordinary garment on screen often hides a great deal of preparation.
