This document discusses and compares two different Doctor Who t-shirt designs - one mainstream and one niche. The mainstream shirt features the TARDIS and Doctor Who logo, making it recognizable and casually wearable by both fans and non-fans. The niche shirt depicts a specific costume from the 1980s classic series, meaning only deep fans familiar with that era would understand the reference. This niche design is bold and not stylized, intended to connect the wearer with other serious fans rather than be casually worn.
