When most people think of green and red as a color combination, images of Christmas trees and holiday ornaments come to mind. However, green and red as a complementary color combination has quite a classic look and if done correctly, can be quite elegant. Here are a few layouts for inspiration.
If you still think that you look like a Christmas card, add a splash of black and/white as accent colors. You can also play with different hues and tones. Have fun, it's fashion! Pair away!!!
