Pirate costumes are one of the easiest to do from stuff in your closet or goodwill!
For him, a flouncy white shirt, a vest, ripped up trousers, get a fake parrot and pin it to his shoulder, eyepatch, mustaches, sword.
For you, you can be a wench, long (or short) maxi skirt, flowy blouse, corset, lots of jewelry, black and white striped top or tights, add on accessories like a bag of coins/compass/spyglass... tied at your waist.
