This is what makes Aquarius so attractive...
Aquarius, ruled by individualistic Uranus, doesn't like to take their cues from others. You may learn fashion rules in order to break them, or just not really care what other people are doing with their look.
In your view, it's boring to be doing and wearing what everyone else is. Your sign is especially touchy when it comes to convention.
Why do bigger people need to wear dark wash jeans? Why can't you mix acid wash green and neon pink, or a tuxedo jacket with a concert tee?
Like the always outspoken Aquarian actress Christina Ricci, only you can come up with combinations that actually work. And they really do, so stick to it!
