I know it's incredibly tiring to flip through pages upon pages of pitchforks and swords I already have unlocked; could we please add a checkbox so we can search the Trade Broker for only avatar items not unlocked?

I often go browsing for something new to wear, but then it's a pain to go through and check each item against the wardrobe to see if I already have it, and something like this would make things much easier.

I'd find this really useful as well. It'd also help prevent accidental purchases.

I agree and then it's easier to find things instead of flipping through pages of things you can't use yet, it's a pain that I would like to be gone.

This could also be helped by a search function in the wardrobe. It wouldn't remove the items from the trade broker, but it would make it easier to cross-check the items you own.
