Dr. Sheldon Cooper, played by Jim Parsons, is highly idiosyncratic, arrogant, paranoid, germaphobic, and altogether insufferable, but his lack of social graces is paired with a beyond-genious intelligence level.
Not to mention, he looks insane when he smiles.
He started college after 5th grade, earned his Ph.D. at sixteen, and loves reminding others of his intellectual superiority. Despite his super-advanced mind, he can be extremely childish when it comes to getting his way. Aside from science, his passions include comic books, video games, sci-fi and fantasy, and paintball.
Sheldon does not care much about fashion, but he is pretty consistent with his love of graphic tees and plaid anything. Layer on long-sleeved shirt under a Green Lantern tee (or one with the superhero of your choice) and top it off with a slouchy striped cardigan. Unless you are feeling daring, full-on plaid pants might be a bit too much; instead, wear a cute pair of plaid wool shorts with tights. Finally, add fun oxford and some quirky extras like a comic book-inspired ring and charm necklace, a reference to "Rock, Paper, Scissors, Lizard, Spock," Sheldon's new and improved version of the game.
Another bright mind is Dr. Leonard Hofstadter, played by Johnny Galecki, in Sheldon's long-suffering roommate and colleague. Although, he is also a theoretical physicist and comic-book/sci-fi/fantasy enthusiast, he yearns for normalcy and a stable love life. He and Penny have their share of an on-and-off-again relationship through the course of the show. His style reflects his desire to fit in: unlike his crazy clad colleagues, he tries to keep his clothing low-key. He typically pairs a graphic tee with a hoodie, cargo jacket, and Converse sneakers.
Howard Wolowitz, at your service...played by Simon Helberg, is an aerospace engineer and the only guy in the group who does not have a Ph.D.; to Howard's chagrin, Sheldon never tires of reminding him of this fact. Howard still lives with his overbearing mother, but fancies himself quite the ladies' man, even though his verging-on-creepy advances are usually rebuffed. Eventually, he find lasting love with Bernadette after they bond over having overprotective mothers. He loves his colored jeans, plaid shirts, and loud belt buckles, but his signature clothing item is definitely the turtleneck.
Dr. Rajest Koothraphalli, played by Kunal Nayyar, is an astrophysicist and Howard's best friend. He is originally from India, where he lived in luxury with his wealthy family. Despite his comparatively meager lifestyle in California, he loves American food and pop culture and is terrified of being deported. Raj is extremely shy and incapable of talking to women when he is sober, but one sip of alcohol and he loses all inhibitions. Raj has a weakness for psychedelic patterns and an impressive collection of sweater vests.
