Bootylicious has had a good run, with gravity-defying help from the likes of Jessica Biel
and, of course, Jennifer Lopez
. Alas, young Hollywood is fickle and the latest body fixation is glam gams. As temperatures have risen, so have the hemlines of Tinseltown and the social set — to heights where a pair of pants wouldn't be unwelcome. For the likes of Penelope Cruz
, Cameron Diaz
and Sienna Miller
, micro minidresses have proved an ideal solution for red-carpet events. Meanwhile, Zoe Kravitz
and Mary-Kate Olsen
have been sporting casual versions of this style, the latter donning what could easily be her boyfriend's shirt. But because these fragment frocks offer little insulation against the autumn chill, expect the shelf life of this look to be very, very short.
