Okay very simply, if I put some clothes I downloaded say for an MP female in my OPENIV, how do I now remove those clothes if I want too, do I delete everything in the folder, and it will come back to default or was I supposed to save an original?

PLEASE tell me I'm not going crazy and doing something wrong, for the latex mod, yellow pants for example are missing and a lot of colours are not there, like screenshots, for the other mod, everything loads, except the fully clothed tights, if someone could verify the same happened with them, at least i can stop figuring this out. Mod is the latex-catsuit-for-mp-female and pantyhose-for-mp-female-matching-shoes

Okay I successfully downloaded this mod https://www.gta5-mods.com/player/basics-leggings I got the leggings, but the thing I need help with is from someone who knows mods. Please tell me why I can not apply these clothing to whoever I want if I set them as my base model. It only applies if I grab either a preset model I downloaded or I go to simple trainer and spawn a free mod 1 something something person from simple trainer, but they all look so hideous. ANOTHER PROBLEM with my preset model I downloaded is that I can change the leg clothing, but as soon as I try to change the tops, it just crops over the one she is already wearing and I see no way to remove that. I mean for some reason even trying to customize their hair, they have limited options. As for my second question when you are placing these files into your OPENIV, and the readme file tells you to go to free open mod etc etc, what I end up seeing is a lot of files that are similar so when I drag my mod files in there is it smart to make a backup because its replacing the files with the same name to give me say the leggings, or is it just adding the leggings. Any help or advice would be appreciated thank you so much, the preset I'm using is this one https://www.gta5-mods.com/player/ultimate-s-mp-female-preset CANT SEEM TO CHANGE ANY TOP OF HERS AND HAIR IS LIMITED TO A FEW OPTIONS ONLY
