Your shoes will be no problem.
A friend owns a clothing store in a small town that boasts a large Mennonite population. She sells very sexy lingerie. I joked about the lack of customers for such items in a small town. She said you'd be surprised at how much lingerie she sells... the Mennonite women buy it more than anyone. From that moment on, I have looked at Mennonite women in a completely different light. Whenever I see them in their plain long dresses, I have no problem with my imagination taking over.)))
