I received a shipment of Nubra like silicone bras the other day and just had to try one out for myself. I have to say that these work really well, much to my surprise (I'm a C). I've since kept one and use it for all my tank tops and plan to use it for an upcoming event where I plan on wearing a semi-backless dress. It's nice, because I'm now liberated to wear all the strapless and backless styles that have been neglected in my closet
