Finally, there's a Google Onesie available at the GoogleStore. It's $11.75, white, and made by Hanes, whose global reputation for high quality childrenswear has made Onesie the bodysuit brand parents ask for by name.
What's that, Onesie is a trademark of the Gerber Childrenswear Corporation, NOT Hanes? While I could google onesie and xerox the results onto a kleenex, then fedex it to them, I'm gonna let Gerber take it up with Google themselves.

There's also a kid-size HanesĘ Beefy-TĘ with an embroidered [classy!] logo for $8.25.
