Getting a tattoo is an exciting and permanent way to express one’s individuality, so it is no surprise that many women choose to get a Gemini tattoo design to show off their dual personalities. Gemini is the third astrological sign of the zodiac, and is often represented by two twins or a pair of butterflies. This symbolizes the duality of the Gemini personality, which tends to be both playful and serious, sociable and introverted, and creative and analytical.
