CERTIFIED OVERTHINKER T-Shirt – Vintage Stamp Seal Graphic Tee

The CERTIFIED OVERTHINKER T-Shirt gives your quirks an official badge of honor. Designed with a distressed circular seal, this bold graphic tee repeats “CERTIFIED OVERTHINKER” around the edges with star separators, framing a large star in the center. The stamped, vintage-inspired style adds a grunge feel that makes the humor stand out without being flashy.

Perfect for adults who thrive on sarcastic self-awareness, this shirt delivers a wink to anyone who knows the endless loop of second-guessing and “what ifs.” Its worn seal look makes it feel like an ironic certificate — one you didn’t ask for, but wear proudly anyway. Whether you connect with it as a funny ADHD shirt, a student’s inside joke, or just an everyday statement piece, the design is both witty and versatile.

Made for a unisex fit, the CERTIFIED OVERTHINKER T-Shirt pairs easily with jeans, joggers, or layered under a jacket for a casual, vintage vibe. It’s also an easy gift for friends, coworkers, or family members who share the habit of analyzing everything twice (and then once more just in case). More than just clothing, it’s a playful way to embrace what makes you unique while sparking a smile from those who get it.
