I absolutely adore tights. No matter what time of year, I almost exclusively wear skirts and dresses and have for as long as I can recall. So when the weather cools, I really look forward to throwing on some tights. Most of my clothes do not have bold patterns, so I like to have tights that are a little more interesting than just sold colors, although I have lots of colors as well. I also like to combine tights with knee high socks in some other pattern when I wear boots (another think I look forward to wearing in the fall).
Here are some good examples of tights I'm enjoying right now, all of which are pretty classic patterns:
Chevron Tights via Anthropologie
Plaid Tights via Modcloth
Houndstooth Tights via Nordstrom
Confetti Metallic Tights via Madewell
Floral Tights via Sock Dreams
and my all time favorite, Polka Dot Tights via J.Crew
