While I like Panache's Cleo line their soft cups give me a really odd shape, like a Madonna cone shape. For the size this bra is the back band is terribly thin and feel on the flimsy side, it's firm on the tightest hooks which is a plus but I'm not sure if it makes up for how unsupported I feel in the back. The bottom front also rises up a bit on me though the gore sits flat. I don't know how often I will wear this, it could end up as an around the house bra.
I absolutely adore the Tango bras. The biggest problems I have with bras is the underwire cutting into my rib despite the bra fitting perfectly, this is no issue with the Tangos as the underwire is really cushioned. The Tango is so comfortable and I've found the band very slow to stretch. The cups have started to fold a bit but I think that might be due to my size changing than the bra.
I'd say the only disadvantage to this style is what is actually looks like. I don't really like the design and find the embroidery on it can easily come through under tighter tops. However I'm willing to compromise on this for the comfortable bliss these bras provide!
