I use the MP clothes addon here:

https://www.gta5-mods.com/misc/mpclothes-addon-clothing-slots


The directory for the clothes and jewelry:

mods\update\x64\dlcpacks\mpclothes\dlc1.rpf\x64\models\cdimages\mpclothes_female.rpf\mp_f_freemode_01_mp_f_clothes_01

(In some cases it's dlc.rpf and sometimes it's dlc1.rpf, pick your poison).


The directory for the shoes:

mods\x64v.rpf\models\cdimages\streamedpeds_mp.rpf\mp_f_freemode_01
