Gemini rules the hands and fingers, so your sign feels sexy (or would) by piling on the bracelets and rings, or even wrapping a colorful scarf around your wrist and wearing it as a cuff.
Likewise, your shoulders and arms are a real focus for you. Cutout tops that show a little shoulder rivet others' attention without showing too much.
If you're worried about sculpting your arms and shoulders so they look their best, think about using hand weights. Small movements can add tone to these areas without adding bulky muscles. Soon, you'll be sporting that beautiful upper body you crave!
