I usually wear a shirt and panties in the evening. Or sometimes a nightgown.
When I lived with my parents, in a highrise with a balcony, I generally wore bra and pants to match, so I could sit on the balcony in what would appear to be a swimsuit.
When I am home alone, usually during the day, I prefer to wear as little as possible. So, please call first before dropping by. 
When the kids are home, I feel I have to wear a bra and at least a nighty, or regular clothes if I have been somewhere that day. (If you have to ask why wear a bra just 'cause your kids are home, you don’t know much about teenage boys). He’ll be off to college in the fall, so that may change.

*Iyyye recommend walking around nekkid in your living rooooooom{/i] . . . whoa, gratuitous Alanis flashback.
Seriously though, I love Joe Boxers. I sort of collect them as a hobby. The louder and tackier the better. My faves are the coffee cups with “one lump or two ?” on them, the strategically placed smiley faces, and of course the baseballs with “home run!”.
Every free born red-blooded male has the right to wear nothing but boxers, sit on the couch on Sundays and watch sports. I read it in the Bible . . . or was it the Koran ?? One of those.

My girlfriend is always naked. She loves naked. She walks in the door and strips down to her bare ass. And she will cook, clean, work, study, sleep, watch TV, organize, laz around, whatever buck naked.
She is always naked, and only puts on clothes if I say “If you don’t stop walking around like that, I’m gonna have to use this one you…”
One would think that this is a cool way to live, but it’s not. I could walk around naked and provide comic relief for her, so it’s not the same.
When she walks around naked, I get terribly aroused, as I am majorly attracted to her. It’s very distracting.
I know, I know, boo-fucking-hoo, everyone wants my life for one second so that their big problem is that their hot-ass girlfriend cooks them dinner in the nude and says they’ll have to wait till later for dessert.
What can I say? She rocks.
