My review of the Topaz Deco Honey applies to this bra too, with the following notable comparison details:
Both bras in the recent versions (early 2014 Cobalt Deco and Topaz Deco Honey) fit exactly the same in the cup for me - same height, same wire length, same depth, same smooth material each with a raised edge(slightly visible under clothing). Where they differ I find is in the band and the straps.
The band on the Cobalt Deco is slightly silky, almost like thick ribbon. The band on the Topaz Honey is lacey, but as a result it's scratchier, tighter and less stretchy. If you have sensitive skin I would recommend the regular Deco over the Honey. after a couple of months of equal wearing of the two, I can report I moved on to the second hook of the Deco and needed to tighten the straps (again, silkier material so a bit more slippy I think), whereas I'm still very happy on loosest hook on Honey.
