The most important factor in deciding what to wear...
Since the element of Water rules your sign, you tend toward colors that resemble the ocean, lakes and rivers.
Shades of blue, green, and mossy yellow remind you to stay in touch with your ruling element, and may even elevate your mood. Muted colors especially highlight Pisces' beauty.
If you find that you need a lift, think about adding a little red or orange to your palette. If you want to delve into spiritual pursuits, add a little purple.
Your sign is so sensitive that color becomes a primary way to shift into whatever you wish to become. Be sure your clothing matches the mindset you want to have.
