The only time my ex-wife wore a bra was when she was working as a carer. Other than that, she was always braless. She was a 36C. Even when we went out to the clubs and bars, she was always braless.
So conservative and never goes out with any cleavage showing, but somehow she hasn't objected to going out without a bra, nor does she notice (or maybe she doesn't care) that her nipples attract men's attention (and no I haven't pointed this out to her!).
