What about mommy's little start up? This seems like most of the start-ups I've come to know. Daddy, the non-technical co-founder just throws in some DNA and management and slaps his name all over the product. Mommy, the technical co-founder and lead engineer, does most of the work and doesn't get any recognition.
Ha! This has been a source of much debate, actually. Most female entrepreneur-friends I spoke with said they'd feel left out, and I hate that. But I had to start with one product, so I figured I'd go for the larger market first, and then expand. I definitely want to give credit where it's due :-)
FYI a few years back when the Where The Wild Things Are movie made onesies super popular again my old company printed some for one of our bands and called them "onesies" - Gerber sent us a cease & desist letter within a month for using their trademark.
Bummer because (infant) bodysuit doesn't have quite the same ring to it.
Ah I see! Sorry I thought I was going to be able to order a onesie (all in one pyjama) with my startup logo/text on it! Congrats on building the site and getting it done though - always good to actually do it rather than just talk about doing it.
You might get away with "Onesies" if you actually use Gerber brand clothes to make your product. You'd need the Gerber logo tag in the product photo and even then they probably won't like it.
For alternatives you can go with one-piece, (baby)jumpsuit, or rompers. Creepers is the term everyone uses in the UK.
