Buy her shirts with wider necks so they go on quickly. I guess that would be mainly v-neck shirts. Pull them on as quickly as you can, and play peek a boo when you take them off, and put them on. I think the dress up clothes that someone else suggested is a good idea too! Also, when you put pull over shirts on her bunch the fabric up around collar as much as you can so that she can see you again instantly. Good luck. I know it can't be easy to find everything with zippers and buttons.
