My reason for my overly obsessed love is that scarves can change up any outfit. They're the perfect accessory. I'm never without a scarf. If I'm not wearing one around my neck, I've got one tied onto my handbag or in my hair. They are super chic and if you get yourself a seasonless one--one that isn't made of wool or too-thin summery fabric--you can get a lot of use out of it all year long.
One of my personal faves is this Abstract Ikat Scarf from Ann Taylor Loft. The color is universally flattering and definitely works for all seasons. The pattern is gorgey, yet it isn't huge and in your face.
This particular scarf is on sale for $15 (marked down from $34). Nice, no?
