I am really happy that I finally purchase reusable silicone nipped covers set by pinky petals. It' very easy to use. The best part is that they can be refued again and again. I always had trouble went I wanted to wear dresses or shirts but I didn't want to wear a bra. Especially when I wanted to feel light . By feeling light I mean sometimes it gets a little hot and wearing a bra can get a little sweaty than threshold nipple covers come very handy. They stick very well and don' move here and there until late u physically remove them. Overall I am very impressed with the quality .
