I too am one of those large-busted women who hates to wear a bra and at home, I rarely do. A while back my husband and I vacationed at a topless-optional resort and it was great! Clothing was required indoors, but by the pool/beach most women had their tops off. Only some of the young, skinny women were too shy to bare their breasts. The rest of us enjoyed the freedom and naturalness and it just wasn’t a big deal. I didn’t wear a bra all week, because I figured if I’d been going around with my breasts uncovered during the day, it really wasn’t a big deal to see some outline of nipple and a bit of jiggle at night. One of the best weeks of my life!
Interestingly, when toplessness for women is normalized, it becomes a lot less sexualized — it’s just bodies.
