I couldn't do that. Although, in the past I've seen a fair number of CDers partially dress in public - and they certainly got the stares. For me, I am more into wanting to look and act as much as possible like a woman when in public, even if I can't pass completely. The ultimate challenge for me is to blend in and be accepted as much as possible as a female - not to actively challenge those around me to accept a partial presentation of such.
Certainly, I support your decision to partially dress and I believe your decision is a brave one, but at the same time I can understand the confusion on the part of strangers around you who might be perplexed by your choice. I know that is their problem and not yours, but as the public is slowly starting to accept crossdressers and transgendered women, I personally wouldn't want to confuse the waters for those who are just beginning to accept us.
