A mod that adds jewelry to a new slot is recommended.

So in vanilla, the most enchantments you could have on a character is 16. 2 for boots, gloves, armor, helmet, circlet, shield, ring, and necklace. And for each individual enchantment you could only have 4 at most.

This mod paired with a jewelry mod you get the full 16 enchantments and are limited to only 4 of the same enchantment, similar to vanilla, but you can feel free to swap armor as often as you like without messing up your build.
