I agree with ReineD. There is no such thing as a cisgender crossdresser. All so-called crossdressers are transgender to some degree. People who claim it's all about the clothes are hilariously out of touch with the truth.
Cisgender people don't dress or behave in significant ways that are commonly associated with the opposite gender. Women who wear clothes that are designed for and sold to women are not crossdressers. Women who wear clothes that were designed for men in a manner that doesn't obscure and isn't intended to obscure their cisgender identities are not crossdressers.
Cisgender crossdressers are like unicorns. They exist in your imagination, but not in the real world.
