Since Sagittarius has been nearly everywhere on the globe, and has plans to visit the rest, your accessories have a global feel to them.
You love your cuff bought in Africa, those earrings purchased in Paris, and scarf hand-painted in Mexico.
Like globetrotter Miley Cyrus, everything you wear is part of who you are, and reminds you of all the great places you've been.
You also need unfussy accents, though. Complicated belts or multi-tier necklaces that just get caught in your hair stress you out.
If you're wearing it, it has to have special meaning to who you are, where you bought it, and who gave it to you - and be comfortable enough to wear all day in pretty much any activity.
