A long time ago I had a bra from Asda of all places, that was just a normal underwired bra, but it had a layer of lace attached that stretched over the cleavage so if you wore a low cut top it was as if you were wearing a vest but without the extra layer. The only similar thing I can find are 'modesty panels' but these are separate to the bra and look a bit naff and a bit of a faff.
Has anybody seen a bra similar to this anywhere recently?
