Big Bang Theory fans love the show for the epic adventures of the funniest nerd duo on earth, Leonard and Sheldon. Our selection of hilarious Big Bang Theory shirts includes designs from the best moments from the series. If you took a closer look inside the pair's apartment, it's likely that Sheldon's shirts would look awfully similar to the ones we stock at Stylin' Online. Even Sheldon's favorite song, with the lyrics "Soft kitty, warm kitty, little ball of fur, happy kitty, sleepy kitty, purr, purr, purr," is featured on some of our Soft Kitty shirts and other merchandise. The adorable, smiling cat that has become an iconic part of the series has made his way into lots of our Big Bang Theory apparel, including a baby snap suit, a hooded sweatshirt and even a lunch box. In addition to a clever gift for the Big Bang Theory fan in your life, these items would make any cat-lover grin ear to ear, just like the lovable Soft Kitty herself.

If a Sheldon shirt doesn't quite satiate your fanaticism, check out our other items that include depictions of your favorite Big Bang Theory characters, including Leonard, Penny and Raj. We even carry Big Bang Theory snugglers with Soft Kitty shown on the head-to-toe blanket, a Soft Kitty bag and Stylin Online exclusive plush dolls. These collector's items show either Leonard or Sheldon and come with a T-shirt to match your favorite character's shirt. There's no better gift for the Big Bang Theory fan out there, and our selection offers a size, fit and color for everyone on your list. Wear your fandom on your sleeve with our selection of BBT T-shirts. Stylin Online is dedicated to quick shipping, and your order is usually sent out in a single business day after your purchase.
