To all LOST fans please do not read any further if you don't want to be spoiled. I was looking through the catalog for the Profiles In History "LOST" Auction and in the season 6 section there is the following description of three full costumes used for the final episode of LOST.
Bonnie, Jen, and Hector Torres' Costumes From The Episode "The End" Bonnie's cream-colored pants, brown/white striped blouse, DHARMA lab coat and shoes. Jen's red button-front dress, belt, DHARMA lab coat and shoes worn. Hector Torres' green pants, green Hawaiin shirt, DHARMA lab coat and shoes.
Since we did not see any scenes in "The End" depicting DHARMA related items or characters I would assume that these characters will show up in the Season 6 bonus footage "New Man In Charge". Season 6 and the Complete Series Collection will be released on August 24th. You can go to http://www.profilesinhistory.com/lost-the-auction.html and download the season 6 section of the catlog to see images of the costumes mentioned. They are on page 25.Lost: The Complete Collection [Blu-ray]
