First, you need to have EMF installed  - https://www.gta5-mods.com/tools/emfsp-easy-mod-folder-for-sp-player-mods

and 

MENYOO trainer - https://www.gta5-mods.com/scripts/menyoo-pc-sp

Instruction

After installing EMF - put all files (the .ytd and .ydd files) into "mods/update/x64/dlcpacks/EMFsingleplayer/dlc.rpf/x64/streamedpeds_players.rpf/player_one"

Note: If you're already familiar using EMF, you can rename the numbers and letters on the file. 

Note 2: You can only use the new clothes via trainer. I only use MENYOO so I cant assure if it works with other trainers.
