That’s a big no. Only a portion of clothes/accessories/etc. on Amazon Prime are also part of Amazon Prime Wardrobe. Starting your search on the APW landing page is the best way to know what qualifies. If you want to search a particular item—say bike shorts or bathing suits—then click the “Prime Wardrobe” checkbox on the left-hand side of the screen to refine your search. Or just shop as you usually do on Amazon and keep an eye out for a “Prime Wardrobe” logo right beneath an item’s price and Prime logo.
