Greys and beiges together with denim make a very nice subtle look. Here I've mixed the two in pieces that are so close, that at times I almost couldn't tell which was which. But it really didn't matter.
I started with the straight leg, dark wash jeans. I then chose the three tone color block cardigan - and this is where the idea really solidified. Then I added the drapey gray top. The shoes and then the handbag came next in their greige tones. Then I added the print frame sunnies and silver and gold jewelry.
