This is all very interesting to me. It's pouring rain and I'm feeling my getup is a little too relaxed or something. On the other hand, I *am* prepared to go outside. What's interesting to me, you've made me all consider more... so here in the US, houses are immediate family for the most part. Parents and kids. I'd see my mum and dad wander into the kitchen in their pjs. They'd be dressed dressed during the day, but still... I mean, even when you move out and get roommates, I think that's the model and you'll get to see your roommates' pjs.
However, my grandparents house was built for more than a nuclear family unit. You were not allowed to come out of your room not capital D dressed. So, lol, I do not come out of my bedroom in anything I can't go to the post office in, just to be safe... without regard to the fact no one is around and the post office is something you only read about in history books.
However, I'm not Dressed. Somewhere in my head I think that means a pressed skirt and blouse, coat, pumps, and a little handbag...
