Right now there is no way to filter "all" as a status in the marketplace. I think this hinders a lot of good possible outcomes. Even on creators profile pages you can't filter "all" for their "My Creations" tab. You can't filter "all" in the main marketplace page. This would allow creators better visibility and possibly more sales. If all wearables are shown, on sale or not, this could lead to more transactions as people would see something they may want to put a bid in on. This is especially important for creators who have been on the platform for a while now and have some older collections that new users might want to collect!
I've attached a visual example. When the filter "all" is enabled, the list should show every single wearable, regardless of sale status or mint supply, in chronological order of when it was published.
