Fit Notes

We use Gerber Onesies® for both white and natural colors. The natural fabric fits true to size, while the white tends to run slightly small. When in doubt, sizing up is a safe bet.

⸻

All of our items are printed using inks that meet CPSIA safety standards and are gentle on sensitive skin. Our Onesies® are made from 100% cotton interlock knit, and our shirts are crafted from either cotton or cotton blends, depending on the brand.

We’re proud to source our materials from manufacturers that prioritize ethical production and fair working conditions.
