All the colors! I prefer red, grey, and black. Only colors I avoid are yellow and orange since they clash with my blonde hair/pale skin but I do really love yellow.
I prefer purple or green, sometimes red. I mainly avoid really bright colors, yellow, orange, and pink because I don't think they look good on me. I avoid white some because I spill things.
I wear quite a bit of blue. I like stripes with white. But I also have brow&teal, red&black and some pretty colorful shirts (dunno what you call them, you know, those patterned ones with buttons). I prefer dark blue jeans with no marks.
I have some shirt&"topping" combinations that I use really often/most of the time becaue I really like them.
I have quite a few colors of shirts that I wear, I usually wear blue or purple though. But I got a new shirt that's half black, then the other side is black with white stripes and it ones of my favorite tee shirts now
