Assuming there is no medical issue going on, which it doesn't sound like there is, I agree with letting her feel more uncomfortable - use regular undies and, if you can find them, the old-fashioned training pants that keep her from soiling the furniture but keep the wetness/pool in.
The other thing you can do - but you must do it matter-of-factly without punishment - is to have her participate in the laundry aspect of her accidents. Okay, this is what we do when we have an accident: we carefully take off the undies and put the poop in the potty, where it belongs. Then we rinse the undies and we put them in the washer or in a basin to soak (whatever you do). Then we put all the other messy clothes in there (her pants, whatever else got soiled or wet). Then we add detergent... Then we have to wash wash wash our hands big time. Make it a huge hassle without there being any punitive sound to your voice. Then go sit down because you are so tired from laundry. Do not reward her with TV or your time. Point out that it took 30 minutes to do all this, or whatever. That would have been a TV show or a game or some coloring time. When she wants to do something with you or her other parent, you apologize and say that you cannot because you are busy cleaning her pretty clothes that she loves so much. You really wish you could go to the museum or for a walk or do a craft, but the housework is just taking all your time right now. You can do those things when she is older and potty trained, when she's ready. That's how it is, big kids get to do more things and, when she's bigger, she can too.
You could also let all her clothes accumulate in a soaking basin or other container, getting out the stains to try to save the clothes, so that she is completely out of her favorite clothes and has to wear things she doesn't love. Again, it's not punishment, it's just reality.
This is tough to do when you and your life partner are both not home during the day, so you will need to completely involve your babysitter or other caregiver. Otherwise you could do it over a long weekend. Keep reinforcing how you love her so much and how you can't wait to begin doing these fun things! It will be so great when she's ready! And so on!
Good luck - I did this with my son for a while before he got the hang of it!
