"High fashion at its very highest. For those who are willing to spend a lot of money to cover up their inadequacies. Fashion never cost so much"
— GTA San Andreas Website.
Didier Sachs is a small, high end, and rather expensive clothing store first seen and used in Grand Theft Auto: San Andreas. The only store in the state is located in Rodeo, Los Santos. It is based upon the real-life Louis Vuitton fashion. Didier Sachs becomes open for business upon the completion of the mission Saint Mark's Bistro. The store and its interior is rather small compared to other accessible clothing stores.
Some online walkthroughs suggest Didier Sachs does not become available until the very end of the game, or possibly even after the end of the game (as a reward for replaying alongside the 100% completion awards), when in fact it becomes available much earlier, following the Saint Marks Bistro mission.
Alex, a girlfriend in GTA IV, has a Didier Sachs background on her blog "liberatedwoman.blogsnobs.org " which shows the pattern of Didier Sachs. It is similar to the one from Louis Vuitton.
