I wore this bra as a 30GG and loved the bra: its look, style and fit with a nice sexy/date-type of bra to wear. Unfortunately, when I received it in the 28J, the bra looked quite ugly compared to my old one with very thick straps. The wires were also too wide for me as were the straps - a usual in UK bras for my size. I quadboobed terribly with the cup being around 2 cups too small, despite me already upping to cup once from my usual 28HH size. The band ran true to size as a 28 band.
The band fits well, but the cups feel small, both in the wire width and the cup volume. The straps are fully adjustable which is good if you're short and need to adjust the straps a lot. Style wise, I personally found it nicer looking in the pictures than in person. I will be exchanging it, but for a completely different bra.
This is one of my favourite bras. Beautiful material, a sexy look yet incredibly comfortable and supportive. I never expected to gain so much support out of a plunge! My rounded breast shape means that I often have problems with the gore fitting the sternum; this one sit further down, and so no poking into breast tissue leaving marks and lays completely flat. The 3-cusps bra band (in bras from GG+) makes the band sits very comfortably around my ribcage, like second skin. Upon changing from an incorrectly measured 34inch to 30inch, after 8 weeks, I have found the band still true to size. Unfortunately, tissue migration has occurred as is now giving a slight quadboob effect. I shall order this bra in a 30H though.
