1. (Left) Turtleneck Sweater, (on sale) $29.99 by Dana Buckman for Kohls at www.kohls.com
2. (Center) Layering Turtleneck, $39.50 from Ann Taylor Loft at www.anntaylorloft.com
3. (Right) DKNY Long sleeve merino turtleneck $145.00 at http://www.dkny.com/
This whole tznius extravaganza at DKNY might be because Donna Karan is Jewish, but it's more likely because they just have a creative stylist.
Either way, I'm a fan.
