These non-photo, outline-only items in your closet (pictured below) are part of a feature we call "Your Recommended Closet". We curate a list of items that would complete your wardrobe based on the information you provide in the quiz when you first opened the Cladwell app. When you add items to your closet, these recommendations will likely be "filled" and disappear. You can also dismiss these recommendations by tapping on the item and choosing "dismiss item".
You can find a list of these items in "Shopping List" within your Closet.
