I haven't worn these yet, but they look like good quality. Not thin and flimsy. I'm excited to wear them at my next festival.
First time wearing pasties and I wear a 34F bra. I watched a YouTube video on how to properly put them on and they worked perfectly, stayed on all night long, even slept in them and I had to peel them off in the morning. I got a ton of compliments on them too.
It stayed all night and loved it!
