Ambrielle, by JC Penney’s. Not certain, but I think this is the Optimum Body Demi model, introduced in 2008. Discontinued along with the entire Ambrielle line in 2012. Wirefree, very smooth with minimal seams. Molded cups have slightly thicker foam padding in lower outside of cups for mild pushup effect. Tagless- the label is not legible; my best guess at the size is 42D.
