I've always admired Calvin Klein's creative director's minimalist side.  Francisco Costa's designs seem feminine and classic without too much fru fru which means Elegance and I love that.  That's why when I saw this two-piece dress in a magazine the other day I went crazy.
I adore the buckles on the back of the dress.  I think it makes it look more chic and modern.  Zoe Saldana chose to wear it with the cropped top making the whole look more dynamic like that.  She has the abs.  I also prefer her choice of pulling up her hair so the buckles show.  You go girl! 
Look at those shoes!
