It baffles me how many one-piece outfits there are out there for female adults and children. Whenever somebody buys my daughters clothing, it seems like about half the time it's some one-piece outfit (Shorts attached to a shirt).
I can only assume that the people who designed these outfits are some super humans who don't have to use the toilet. In any case, I just cut the shorts bottom off to make them into a dress.
The worst is one piece bathing suits. Because I'm sure everybody loves having to take every stitch of your child's clothing off so that they can pee. Which, if there anything like my daughter, they have to do on an hourly basis.
Another benefit to being a female....
