I take a 30gg or h depending on the bra and can only wear a plunge style. I wear a Bravisimo Satine for work as it gives a nice shape but it's not particularly pushy-uppy for when I want major cleavage. Freya Deco gives the look I want but it's far too high under the arms and really chafes. I used to love the Freya Retro Basic but they don't make it anymore.
Can anyone suggest an alternative?
