I once saw, I think in Threads,  a Women's t-shirt that had overlapping triangles (slightly gathered) attached to a bottom panel.  The bodice pieces just over-lapped, there were sleeves.   I am looking for something like ti to make a nursing top for my daughter by sewing a panel inside the vee to fill the decolte but which could be un-(hooked)snapped for nursing.  Any help out there?
