I Love Math Long Sleeve Baby Onesie

Girls' shirts with awful slogans like "Allergic to Algebra” and “I’m Too Pretty To Do Math” inspired our math-positive design. Math is beautiful, and we think it should be equally embraced and celebrated by kids of all genders. 

Fashionable Garments, Ethically Produced.

All of our clothes are designed in Seattle, guaranteed sweatshop-free, and printed by hand with tons of love in Seattle. This onesie is ethically produced in India in a Worldwide Responsible Accredited Productioncertified facility.

Sizing & Fit

Our adorable, super soft long sleeve baby onesie runs true to size. It will shrink a bit the first time it is washed and dried. Babies grow fast, so when in doubt we always recommend ordering a size or two up!
