When time is in a crunch and a look of glam is in order for the evening, try a sleek and sexy low ponytail like Blake Lively's.
Pretty make-up and some earrings with bling add to the formal edge that this hairdo has. Unwashed hair works better for this style as the strands tend to be less whispy this way and adding some pomade to the crown area adds to the sleek and shiny appeal.
