Depending upon my clothing choices I'm beginning to hit male fail periodically. I do wear mostly female clothing but more toward the androgynous side. Besides my wife, therapist and local T group I'm not out yet and still have to present male-ish as much as I can anyway. The only article of clothing that is typically male that I wear on a regular basis is my outer shirt (under neath I'm wearing bra and cami everyday now to protect my A cup breasts and to try to cut down on the visible profile).
Last weekend I got ma'am at the grocery store several times.
Today, I went out to lunch and then shoe shopping with my mtf transgender friend (she's more like my big sister at the moment). We had a great time and were called ladies, miss and ma'am the whole time.
All without realy trying to pass - no make up, no breast forms. Just me au natural...

I'm still on cloud 9
