* Something that encourages their creativity. Aquarius girls are often very creative and artistic, so they'll appreciate a gift that allows them to express themselves. Consider getting them a set of art supplies, a musical instrument, or a ticket to a concert or play.
* Something that helps them relax. Aquarius girls can sometimes be stressed and anxious, so they'll appreciate a gift that helps them relax and de-stress. Consider getting them a gift certificate for a massage or spa day, a book on meditation or yoga, or a set of essential oils.
* Something that shows you care. No matter what you choose, the most important thing is to show your Aquarius girl that you care. Make sure to wrap her gift nicely and include a heartfelt card.
