Check out the tiny undies, smaller sized training pants (non-waterproof), and pants for little ones who don't wear diapers at the following mother-owned-and-operated store (not me - I've just purchased from her before and been really happy with the undies I ordered):

And a *huge* congratulations to you for noticing and honoring your daughter's readiness signs - these days, so many people ignore signs of toileting readiness because current western opinion tells them "that's too early" when, in fact, babies know from very early on when they have to pee/poop (and there are several windows of readiness, including big windows at 12 months and 18 months). So, yay for you and your daughter! :)
