I think 2 is a bit young for potty training, but that's just me. I have a 3 year old and when her 3rd birthday was getting close, I started talking about how she would be a big girl when she was 3 and would get to wear beautiful big girl panties and use the big girl potty.
I tried to get her excited about it and made it something for her to look forward to. I also always took her to the bathroom with me when I went. The little 'potty' was in there for a couple months prior to her turning 3, so she could sit on it and get used to it, even with her clothes on, if she wanted to.
On her 3rd birthday, I presented her with several pair or big girl panties with her favorite characters on them. No more pull ups! She only had a few accidents, and very quickly got the hang of the potty. Now, only 4 months later, she uses the 'big potty' and cleans herself and then gets on a stool and washes her hands!
If your little one keep stripping, maybe she is uncomfortable? Bored? Try giving her things to do and interaction with her more and see if that helps. Let her take her dolls to the potty, and keep encouraging her to tell you if she has to go too.
Maybe the 3rd birthday approach would work for you?
Good luck!
