What stands out is the double elastic on the back, it keeps it stable, it is soft and pleasant. I can't tell you about the cup because it came too big for me, I found the material quite fragile, I was disappointed in relation to the brand, it doesn't have a long lifespan, especially for relatively heavy breasts, nor does it have a wide range in the perimeter elastics. Overall, it's all about new materials and technologies, but we're not little girls to buy one every, for example, six months... but we don't buy classic designs from our grandmother's time either, which are definitely more durable, beautiful, and feminine
