I've had my pair of new-style Porcelain bras for a few months now, so I thought I'd weigh in on the discussion of the new style.
It sucks. I could never have imagined feeling so genuinely gutted about a bra. Bravissimo should change the description, because this style used to be the 'best t-shirt bra we've ever worn', but this is NOT THE SAME BRA. Literally everything that was good about it has changed. The straps are wider and uncomfortable, not the soft and elegant straps they used to be. The way they are attached to the cup is also very different: it used to be a smooth transition with the strap kind of continuing along the side, now they are just sewn together.
The shape of the cups is weird and not as flattering, certainly not as comfortable as before. The material is more stiff and the fabric more shiny. After a few washes, the cups on both of my new-style bras began to lose their shape so that the edges are turned outward and are showing under every t-shirt. Sweat and water stains now show very easily.
This is NOT the same bra and I am sorry, but they are not equivalent. The original was perfect, this is a fraud. Gutted!
