I had the exact same questions when we got our Katie Scarlett and I will tell you what everyone told me...persistance! You just gotta keep on it, everyday. If they nip at it or even take it off/out, put it right back on or right back up. Katie Scarlett used to chew at her sweaters and I would say 'no no.' After about 2 weeks, she finally just gave in. Now she knows every morning we do our grooming and then put on our sweater/dress/etc. for the day. I think she even looks forward to it now. As for the top knot, just keep on it. If they take it out, put it right back up. It can be frustrating, but just stay persistant. I am living proof...it works! I had a time with Katie Scarlett leaving her top knot in but now it's like clothes...she just lays there and lets me. With her I found that she doesn't mind the bands at all, but if I use a clip or a bow, she throws the biggest fit. So we do a band every single day and I am working on getting her used to bows. We haven't mastered that yet, but I have confidence we will. Just keep on doing what you are doing and all your hard work will pay off hopefully! Good luck!
