There's one thing Leos should always wear...Since Leo is such a fan of adventure, you may find that ethnic or unique patterns can round out your look.
Bold colors and accent pieces like earrings, cuffs, and even studded belts can bring a little edge while still keeping you looking classy.
Think about how to express the person you feel like today (since that's ever changing) with accessories. You don't have to shout when you enter the room. Let your style do that. People will know what kind of person you are, or aspire to be, based on your accessories. They make you and your outfit that much more special.
