First, I am firmly in the dress for the way I feel camp instead of the trying to pass camp, so bear that in mind...
I find my need to dress is fairly constant at some level. Some days, I do really need to go all out but for the most part, my feminine side just needs a little acknowledgement.
To that end, I do what I call "Stealth Dressing." I wear panties 24/7 and have found a few female clothing items I can wear in guy mode that, so far, have not aroused any noticeable responses.
For example, I wear tank top style under shirts and have found that I can wear women's tanks and not only are they much softer and come in a wider variety of colors, I actually like the fit better than the men's.
I have also found a brand of women's jeans(Eddie Bauer) that fit perfectly and have figured out that if I wear a sports bra under my tank top, the straps don't show, my man boobs are less prominent and nobody seems to notice.
Now I will admit that I may have totally outed myself to the entire civilized world, but, using my ex-wife as the barometer, if it were noticeable, Vesuvius would have been a minor eruption...
Just curious what, if anything, others may do to accomplish this...
