Question for those of you who have purchased costumes from the store: Can you choose which parts to wear?

This costume looks awesome on my female Redguard, and makes her look kinda piratey. There's no head item with this outfit though, so if I found an eye patch or pirate hat in-game, could I wear that on top? Or does wearing an outfit mean that's it, nothing else will show, and there's no customization options here at all?
