If you want a tattoo that represents your sign, you have plenty of options from which to choose.
One of the classics is the Aquarius Zodiac symbol. Two lines of waves represent Aquarius. This simple design can be great for tiny tattoo ideas or for larger pieces that incorporate other elements.
You can even stylize the Zodiac symbol how you like it. It can be as simplistic or as colorful and brash as you want it.
You could even go straight for the source and use the Aquarius constellation as your design. Again, this could be as simplistic or as intricate as you like. For example, you could have a tattoo of the entire night sky. The constellation is the part that shines the most brightly in the entire piece.
Because the Aquarius sign is an air sign, it can be difficult for some to think of a way to represent that in physical form. One such way might be a powerful gust of wind across a barren landscape or a lush landscape. You may display the gentle breeze of air with the addition of flower petals dancing in the wind.
Or, for those who love color, you may use clouds of sheer color to showcase your vibrant Aquarius personality. Sweeping swirls of color can not only display your status as an Aquarius but can also create an enriching landscape that looks mystical and otherworldly. Sticking with bright shades can add in an airy element.
Perhaps you knew someone special who was an Aquarius and proud of their sign. You can always choose to honor them with a portrait or design that somehow incorporates the image of the sign within it.
