I actually really don't mind wearing a bra. I wear one daily, the only time I don't wear one is when I am in my pjs.
I have 36D breasts, so for me the support my bras give me is amazing,.. In the past I have had a professional bra fitting and that lady told me, if you wear the right size bra, it will feel like you are not wearing one.. that fitting revealed I was wearing the wrong cup and band size. The first time I tried on a 36D bra, it was amazing how comfortable the bra was.
