This might be an unpopular opinion but i like them being a fashion oriented item.
I like the concept of some items having more uses than others. I don't mind if some are inneficient or even kinda useless. Yes, there are some items that are always used, others that are more of a niche but its cool too when items dont fulfill any specific purpose (also its a recipe item).
When speaking of the fashion goggles, they are fashionable and followers can use them... need a use? upgrade them then.
Having said this, there are many cool concept ideas mentioned for the fashion goggles that i wouldnt mind being implemented as well!
