Title says it all.

subscribe to LivingEquipmentChangeEvent. then add the Effect if the Item with your conditions is the new Item for the Slot,
if the new Item equals old Item do nothing, else remove the Effect

Okay I will try that

Hey, how would I go about apply the enchanted effect?, also I don't want the armor to be enchanted I just want it to look enchanted when wearing it.

this is handled by Item#isFoil, but the method does not provide a Player so you need to replace the way vanilla renders the Armor

As far as I can see, Item#isFoil is only executed on the client (in vanilla code), that would mean that you would get a player via Minecraft.getInstance().player
so you be able to check if the Player is wearing your Item, note you should make a check if you are really on client via:

FMLEnvironment.dist == Dist.CLIENT

note you also need to handle a else case, means a other Mod is calling Item#isFoil on server
