Of course. I use sunscreen and I use organic coconut oil as a mositurizer. There's nothing wrong with taking care of yourself or papmering yourself. In fact, pampering yourself is a good thing. My objection to the creams, etc. are more about the false claims many of them make.
As for bras, if I had anything requiring support, I suppose I'd wear one. You have to have decent sheets, jeppers, that's a given as is a decent pillow (should you be able to find one)!
I also pamper myself, it's necessary.
