People have always told you that you shouldn’t keep things inside. That you should let them out.

But your stomach and lungs? Is that weird?

Apparently not. Blood Is the New Black, the T-shirt collection currently featuring the work of Keren Richter and Andrea Shear, lets you unbottle your emotions (er, organs) and wear images of your innards (yes, innards) on your sleeve.

The line began as a concept to make art more accessible. Artists began putting their artwork on tees — the most ubiquitous of canvases — and things kinda took off from there. Current designs range from cute pop-art animals and figures to those of the more of the internal-organ variety. Different aesthetics to suit different tastes.

So let us know how you feel.

Whether it’s warm and fuzzy or just anatomically correct.
