As the sign of the Twins, Gemini tends to have a lot of interests, fashion and beauty among them.
You care about what's on the surface, and want to make a good impression on everyone you meet. That may mean mixing patterns, trying bold prints, or finding a signature color that makes your eyes pop.
For a Gemini, self-expression is everything. They need to communicate who they are at all times. Even if your patterns seem to be clashing to others, as long as they look good to you and boost your confidence, they're just making you that much more unique.
