Is it rude for my family to say not wearing a bra is bad taste?

What does everyone think about this?

Should family be able to tell me that me not wearing a bra is in poor taste?

I think its quite rude to say that and has made me very self conscious which I already was. I feel it was not very nice to tell me this

PS I don't even have large breasts if that matters

And why do guys and people in general think nipples are bad taste if seen when braless?
