In the season 7 premiere, “The Hofstadter Insufficiency,” Sheldon tells Penny in a forced bonding session that he owns nine pairs of pants and nine pairs of underpants. If you, too, have nine pairs of pants, then you’re off to a great start in mimicking Sheldon’s unique, fun style of dress.
Sheldon does his laundry every Saturday night, so he needs enough shirts to get through the week in any given season. His favorite look is layered: a long sleeve monochrome t-shirt underneath a short sleeve t-shirt often brightly colored with a superhero graphic or science-related saying on the front. His “73” shirt is often portrayed on the show (because 73 is the perfect number), and lightning bolts that signify his hero, The Flash.
If you have a favorite one in mind that you’ve often seen on the show, SheldonShirts.com can help you find what you’re looking for.
When Penny sneaks into Sheldon’s room for some online gaming advice late one night in Season 2 Episode 3, “The Barbarian Sublimation,” Sheldon warns her that he’s not wearing any pajama bottoms. Why? Because he spilled grape juice on them and to put on another pair, as Penny suggests, wouldn’t make sense because these are his Monday pajamas.
Though his pajamas are not marked (at least not visibly, in any case) according to the day they are worn, dressing like Sheldon means having a pair of pajamas, complete with t-shirt and long pants, for each day of the week.
Sheldon’s costume of choice is The Flash, but he’s been known to dress up as The Doppler Effect, Raggedy C3PO (due to a “compromise” with girlfriend Amy Farrah Fowler), and others. If you’d like to dress up as Sheldon as his favorite character, the simplest way to go is a manufactured The Flash costume and the cheapest way to go is the Doppler Effect (simply don a shirt with black and white vertical stripes in a progressive pattern).
Despite his brightly colored tees, Sheldon’s style is primarily conservative and functional. He wears a messenger bag to and from work and keeps his hair cut short. No jewelry, no hats – unless it’s winter in Bozeman, Montana and he’s fleeing Pasadena for what he believes will be a crime-free environment as per Season 3 Episode 13, “The Bozeman Reaction” – and plain front gray or khaki pants.
For special occasions, he now has a nice black suit that Penny helped him pick out but if he had his druthers, he would have gone with a loud black and white checked suit, in Season 3 Episode 18, “The Pants Alternative,” so you could go with either one for your Sheldon-style fancy event.
And, if you’re just a fan of Sheldon and the show, you can always opt for a Bazinga! t-shirt and, remember, if anyone second guesses your style simply remind them: “I’m not crazy. My mother had me tested!”
