You won’t need a bra as most of the gowns will have built-in bra cups, but feel free to wear nude coloured nipple pasties if you are more comfortable. We recommend nude coloured seamless underwear- high waisted ones are often best! Highly recommend Spanx High cut seamless thong, and SKIMS low back shorts! It’s usually ideal to size up in shape wear so it’s more comfortable if you are wanting to buy some- but you don’t need to! Any beige coloured underwear will do!
