The Big Bang Theory airs Thursdays at 8/7c on CBS.
Sheldon wears short-sleeved graphic t-shirts with nerdy scientific or pop cultural imagery over long-sleeved t-shirts.
Throughout The Big Bang Theory’s 12 seasons, Sheldon Cooper (Jim Parsons) has maintained his live-action cartoon character appearance in two main ways: one, Jim Parsons’ ageless face; and two, his signature wardrobe.
