dressing.

Personally, I'm wearing women's clothes all the time. Mostly pants and femme shirts/tops(with a varied range of undergarments including bras, panties, tights, etc.), so it's not really obvious. At home I'll often wear skirts. And for night play, often really fun stuff.
How I'm dressed really depends on what I'm going to do, and with whom I'm going to do it.
So, in a general sense, all the time because that feels natural to me. In a sense of getting "dolled up", not so often, but certainly 1-3 times/wk. Would be more if we lived somewhere more liberal.
My wife has no issue with the whole thing.
