My cravings often vary. I think this is because I am not a trend follower. I purchase/covet based on my gut reaction to a product and my visualization of how I would not only wear, but also live in a particular style.
I use the same approach when I look at interiors and home decor.
Lately, I've been on a skirt kick ... I visualize pairing them with tall and ankle boots as well as peep toe booties.
