Another collection that comes to mind when I think 70s-inspired is Cynthia Steffe spring 2011.
Wide leg pants, pant suits
Tan-orange color scheme, geometric prints
Short shorts, halter necklines
One-pieces, one-shoulder cuts
Cynthia Steffe is a Sugar Rock Catwalk favorite as the line is perfect example of fem with a little twist (and they have the best sample sales). The spring 2011 collection is super wearable and definitely something I want to own. I like the flowy frocks, but I especially love the more structured separates like the leather shorts and jackets. And as always, I'm a fan of the prints and color blocking!
You can find Cynthia Steffe at retailers like Saks and Bloomingdales.
