Another trend that was showcased for Fall 2010 is color minimalism - using one color throughout the whole outfit.
Though this may appear boring to many people, I really like this look because it makes you focus on the person's face more than their body. Also, this will help make getting dressed easier because you can just layer black on black or beige on beige and be set. Most women I know love black, so this will keep you in your comfort zone and help avoid having to purchase more clothes.
It is, however, a big swing to the right since summer and spring are full of floral patterns juxtaposed with stripes, plaid and gingham.
