i've own this exact bra in size B with the same packaging. i'm a 34B. i've worn this bra a few times for a few hours, but today, i worn this bra without a strapless bra for 12 hours today. still sticky adhesive, comfortable. its like i'm wearing nothing, yet wearing a strapless bra! i've never worn this bra without a strapless bra before, so i was very impressed how effective this product is. i wish i bought this product at the Amazon price of $7. wow... i bought this product $30 a few years ago! i'm not a girlie girl and i didn't even know this product existed, so i had no idea to look for the cheapest price.
