Options, Variants And Features - Confusing

Morning

I am getting a little confused when it comes to the different ways to add sizes. If my vendors add options in how do they manage the inventory of each option? If I add sizes as a feature they can add that and then add inventory but they can't add their own features?

I have tried reading the guide but getting super confused by it all

Any help to explain it to an idiot would be great

Thanks

Dont beat yourself, you are not an idiot. There some obvious design flaws and a lot of declutter to do.

Ð’o you want to allow vendors to add features or variants for existent features?
