this is just like the identical looking model, Vanity Fair Women's Beauty Back Full Figure Underwire Bra #76380 - BUT the cup is not a fixed cup.  just the fabric of the cup is a stretchy fabric much like a sports bra.  personally, i think it's wonderful!  it does give a different shape, but that's how it minimizes. i am of the opinion that this is helpful for keeping the skin in better shape when losing weight.
this bra is exactly what i was looking for back when i was a C.  i'm glad to have it now.
i had to go up in size bc i packed on a load of weight due to health issues.  i think this bra will follow me better as i lose the weight, instead of leaving me with partly empty cups like other bras do when i reduce.
