Runs small

I like the tshirt but it runs too small! I will need to send it back. The print isn’t as dark as shown. 😢

Gotta Love a Science Shirt

I love the design on this shirt, as well as on the cephalopod shirt that I ordered. The color is nice, the art is not cartoony, and the fabric feels good. My only gripe is that the shirt was a little more tight than I was expecting. It's not distractingly tight, and the length of the shirt is appropriate, I'm just more partial to looser shirts that aren't too big to be pajama shirts. Other than that- great product and speedy delivery.

Size runs big and shark tee is light blue

I’ve been searching for a shirt like this and so happy to support this company. For future customers, this shirt is a light blue color. I originally thought it was white as it was difficult for me to tell in the pics and wasn’t clearly written in the description. I don’t mind at all but just so others know. Also, as other reviewers mentioned, the shirts run a bit larger. I’m 115lbs, 5’1” and got a S. I don’t like shirts tight on me (I almost ordered a Med and happy I didn’t) so it’s perfect for me. But if you like a tighter fitted Tee, I would opt for XS if your close to my size. Tee is very comfy.
Would be nice to pick t-shirt colors - just a suggestion for the company if there interested.
