In the remastered version of this game, this trophy is nearly unmissable.
The remastered version of the game comes with all DLC, which awards the player with 8 pieces of gear in chapter 4, right at the beginning in the Blue Ribbon Restaurant (the one where you receive your first infusion from the Luteces).
The only way you can possibly miss this is if you don't pick up the gear from the tables before you take your infusion.
