It's a fancy-looking dartboard. Just kidding. As a musician, you will definitely appreciate this beautiful Circle of Fifths, especially if you ever struggle with the sharps and flats. From now on, changing keys will be much more fluent in front of a mirror. However, you probably won’t be allowed to wear this to your music school exam.

This t-shirt is everything you've dreamed of and more. It feels soft and lightweight, with the right amount of stretch. It's comfortable and flattering for both men and women.

Did you know our t-shirts are available exclusively online? You won’t find them in a high-street shop. Dazzle your friends in a bespoke design.

Shipping: you should get a package from Optimist Collective within 7 business days. Though since most of the post services are still affected by the pandemic, delays can be expected.
