Guys- do you wear pajamas to bed/around the house?

I'm a guy in his mid 50's who loves to wear 'formal' pajamas at home. This is a plaid, two piece set with buttons, etc. I call this my 'house suit'. I would iron these pajamas if I didn't think my family would call me crazy.

I'm sitting here in my pajamas, robe, and slippers- warm and comfortable in front of the fire, wondering what other guys are wearing at home.

I like to wear something that is comfortable, but also if people who are close to the family come over, I'm fine with them seeing me like this.

My 16 year old daughter's friends saw me and their (probably a little sarcastic) reaction is, 'cool pajamas'.

Wondering if anyone else wears a formal set of matching pajamas. Or, what would you wear if you were visiting someone else's house and you were in a situation of wearing your sleeping clothes in front of other people- what would you wear?
