I've seen several odds and ends items that are wearable, but I was just wondering if there was a comprehensive list of wearables anywhere?

You can go to your wardrobe and change the "Use Clothes From:" bar to "All Clothing on Subeta"

There are TONS of wearables, so short of using the "All Clothing" section of the wardrobe or something no I doubt there's any kind of list anywhere. However there are lists of tribute items and tribute CWs. If you're looking for something specific, So Fetch or Subetalodge may help. So Fetch is an avatar creator while Subetalodge keeps tabs on Subeta items (among other things) and you can search by name, description, restock location, etc. since names of items might be misleading depending on what you're looking for.
