In general, you should never have to wear any underwear under your swimsuit. If it is a one piece, you don't need to wear a bra or panties. If it is swim trunks, swim shorts or swim briefs, you usually shouldn't wear underwear underneath those either.Oct 22, 2020
Can you add padding to a swimsuit?
If you want to add some padding, make sure it goes well with your suit, creates a natural look, and won't shift when you move. Some suits come with built-in padding, which can be wonderful for anyone with a petite bosom. Swimsuits with adjustable straps are also nice for enhancing your bust.
How do you attach bra padding to a swimsuit?
To insert foam bra pads into the top, fold the bra pad in half (like a soft taco), ease it through the gap and wiggle it into place. It should fit snugly into the bra area. If it's still a bit roomy and you're worried the pad might move, simply sew or pin the pads in place (foam pads only – never pin silicone).
How do you add cups to a one piece swimsuit?
Cut your bra in half through the center and cut off the straps. Cut an X in the cups of your swimsuit lining (the size of the X will vary with your bust size), push the bra cups up into the X, and pin them in place.Jul 14, 2015
