Yes, of course, bra pads can be set within a swimsuit before wearing it. Also, you can wear the bra pads separately before you don your bathing suits for sagging breasts. Doing it doesn't only enhance your cup size to make your upper part look sexier but also helps to uplift your saggy breasts more and give extra protection to them so that they don't fall. Besides, wearing bra pads in addition to swimwear smoothen and shape your breasts even better.
