Most Helpful Guy
Not really. I'll just assume it's your Dads, and feel really awkward. Then I'd have to ask myself, why am I in your room, in your bed, and judging what you are wearing. Then I'll probably have some kind of breakdown and pop my bolt. Not in the good way.
Meh. My girlfriend wears cute pyjamas, or in some cases, a nightie, with knickers on in both cases, anyway. It's generally more modest and kind of safe when you consider having one of those turns in bed, and someone checking on you, only to find your legs spread, sticking out from the side of the blanket, or something. Depends where you live.
I think I prefer the nightie and knickers thing, myself. It's cute and that makes me like it more. I guess at the right times, wearing nothing but a shirt would be attractive, but not always. For me, anyway.
