American Apparel's Lace Unitard

Hmmm ok so I saw this American Apparel  ad and it caught my attention.  I mean a girl scantily clad in nothing but a lace unitard is not something you see everyday (in most professions that is).  I am still not yet sure what the point of this piece is.  What purpose does it serve?  Should you layer it?  Belt it? Maybe pair it with a scarf?  Or maybe take a cue from J-Lo and rock the Louboutins with it?
