Short version- Like the standard Porcelain, the band is not continuous, and the cups are seamless and molded. The contour material is a good deal thinner than an EM plunge or Freya Deco or padded half-cup, which has its ups and downs (feels lighter, but less nipple modesty). Fully adjustable straps!
This bra stays in place during the day, and I had only a bit of spillage towards the middle after several hours (so far true of all plunge bras I’ve tried, because my tissue is on the soft side). The band is what I would call an ‘average’ 32, does not come up tight as many Panache bras do, but not as stretchy as the Freya bras I’ve worn. The straps did not seem as widely set as the standard Porcelain, but one’s mileage may vary. The cups fit just right in a 32G (what I wear in the majority of bras).
There is fabric at the bottom of the cup where it doesn’t curve out at all, but this seems to be the design to provide support. It didn’t feel like the orange-in-a-glass effect which I get with some bras that have very little room at the bottom of the cup. The fabric doesn’t fold over, just tacks against the skin. It may not be for everyone, but suited me just fine and was calibrated for the appropriate size.
Smooth and sleek, this works great for me under fitted or knit tops. The Porcelain Plunge doesn’t give my breasts a ton of lift or projection, but the shape is pretty round and front-and-center.
