Investigation Discovery joins forces with reporters from People magazine to tell stories of high-end fashion icons and their couture crimes that captured headlines. The adage"if looks could kill" takes on entirely unique meaning in the series, which grants People's journalists exclusive access beyond the catwalk to reveal that fashion can sometimes be fatal. The hourlong tales of depravity, obsession, and family betrayal in the fashion world all have a common thread -- cold-blooded murder.
