One thing we've found from our years of bra fitting is that deep plunging bras are a) a wardrobe necessity and b) frequently hard to fit. Unless you are pretty full up top, low spacers often gape open at the top of the cup. Ugh. The genius designers of Natori have taken this into account with an inspired layer of stretch mesh overlapping the delicate molding of the otherwise spare cups. The center plunges, the cups lift and oomph, and the mesh makes sure everything lies flat. If it weren't so darn sexy we'd say this might be the most brilliant basic we've seen in a while.
