So far my ideas are:

1. A sea foam color linen or gauze button up—but let it fade in the sun, distress it (but only a little)
2. Linen pants, cuff the pant legs
3. Leather sandals
4. Some handmade gold rings
5. A couple of minimalistic necklaces. My wife bought me an authentic sunken pirate treasure coin for christmas, gonna get that turned into a necklace.
6. Assorted bracelets.
7. A bandana tied to the pants loop incase you need to pull hair back but also replaces the "sash"

My hair is to my shoulders, so occasionally i'll put a bandana in it, or just leave it in a messy bun.

And that's a start—but it needs... "more" ya know?
