Of course you are free to wear any type of swim top you choose, but even after your breast lift, your breast skin is still the same in terms of genetic makeup, collagen content, and elasticity (or lack thereof) as before your lift surgery. Thus, over time and with aging, your remaining breast skin will continue to (re)stretch and (re)sag to some degree.You have wisely chosen to wear underwire brassieres for support of your breasts, and would be smart to continue to do so. But you don't HAVE to, and you can choose to not buy underwire bathing suits. But use underwires the remainder of the time. Even if you're a beach/river/pool rat who "lives" on the water, I suspect your "regular clothes" time exceeds your swim suit time. Good compromise. You can still choose anything you wish, but supporting the skin you were born with remains a good idea for longest-lasting results! Don't worry; I still suspect you'll have the best breasts in the nursing home someday! Best wishes! Dr. Tholen
