I read that this bra ran very narrow, deep and generously, but it still isn't quite right for me. The band seems to get looser in higher cup sizes - this fits more like a 32 band, so I'd say it fits like a "standard" 32JJ. The wires are definitely narrow, but I wouldn't say it's particularly deep in this size. It doesn't bring you up and centre, it's more of an hourglass-from-the-front bra.
I found the wires to dig into my armpit horribly, so much I'm considering unpicking the wire channel and shortening the wire, though the sides would still come up too high. Apparently some other colourways are lower at the arm, so I might have to look for those. I will say that the wires are very firm, so they stay U-shaped, rather than stretching back with the band. The gore doesn't sit flat on me, and if I hold it flat it's clear I need about a cup up. I might try bending the wires to see if it relieves the armpit digging/floating gore, but I don't know if I'm going to buy any more of this style. Ideally I think I'd need a 28L in this bra, rather than my proper size of 30KK.
