We bought my son some 'Bob the Builder' and 'Thomas the Tank Engine' 'big boy' pants and suggested to him that he wouldn't really want to get his Bob pants wet and that perhaps he could try to visit the toilet more often. A reward chart was a big help too, a star for each dry day, a small present for 10 stars - DO NOT stress out over days when she does not achieve a star though, it puts too much pressure on them.
