Miss Oops Show Stoppers ($16). They say: These reusable silicone nipple covers are the perfect weapon to prevent “perk out.” Show Stoppers are tapered at the edges making them invisible under garments. Plus Show Stoppers are reusable up to 15 times. Marta says: “They are right! It is very reusable. The silicon makes it feel like second skin and gives your “perk outs” a natural & seamless look. All in all, it saves your wallet and your outfit. LOVE:)”
