Kim Kardashian  and her sister Kourtney wore matching white Juicy Couture  track suits as they left their hotel in Montecito today. The duo were headed to the wedding  venue, a private estate, where Kim will get ready for her big day. Their mom, Kris Jenner, was also spotted on her way to the event while Kim's stepdad Bruce was busy picking up a coffee in town earlier this morning. Bruce was also decked out in a white outfit, though all eyes will soon be on Kim and her groom, Kris Humphries. Kris will wear a custom white Ermenegildo Zegna  tuxedo jacket and black pants, and his groomsmen will be in black tuxes from the same designer. Details on Kim's dress  have been kept quiet, but she did share that she had help from pal Nicole Richie  in choosing the style, which she says will be more "old Hollywood" than trendy.
