They're back, in full force. I think it's a trend we can be thankful for: a turtleneck adds a welcome layer of warmth and yet almost disappears underneath more interesting pieces. A turtleneck also extends the wearability of our spring and summer clothes--and gives them a cool new look, to boot. The key to success though is a turtleneck that's lightweight and thin, so you don't add too much bulk to your outfit. I just ordered this in white.
