I can't pass as a woman, but I can come pretty close - so I just dress appropriately and blend.
Some can tell, many can't. Either way I don't mind, and I enjoy it immensely. And the odd compliment which comes my way is always welcome.
EDIT: So I went to the mall today, dressed in a pink top and my new skirt (a 'first'). Also sandals and black knee-highs, and my grey wig. Forms in a 14D bra. Jewellery and bright red nails. Just walked in and proceeded to go about my business. And no-one gave me a second (or even first) glance.
I did see one GG that I know, but who does not know about Wendy. She didn't give me a second look either.
