Lingerie of the Day's sexy little number by Dans La Nuit.  Here I am wearing the Karma Bustier and matching panties made of nylon lace.  The underwire supports your natural form and has a cute little jewel hanging between the cups.  The briefs are very low cut and made from stretch nylon to move with your bum so as not to cut in or ride up.  Some other details I think are adorable are the lace covered bra straps and tiny black bows hidden throughout the piece.  

The fit of the bra is true to size although I would go a size up in the briefs.
