More plain clothing that isn't a pain to unlock

Maybe add more generic clothing available from the start, like plain white/black socks and shirts instead of locking them to loot cases or even just not having these items in the game at all. It is incredibly hard to have even a simple outfit when all the socks the game is giving me is like neon green and pink or something when I just want a plain pair of black socks. I cant imagine its very costly or hard to make a simple pair of socks free for all but that's all I'm suggesting

like earlier I unlocked a plain grey t shirt after like 20 hours of playing the game, maybe that should've been available from the start?
