Good material. Good for layering. The cut make this top super versatile: I can see myself wearing it in the office with black slacks or over a rugged pair of jeans. Overall, I'm so pleased with the quality-for-price ratio of this top that I'm already planning to buy a couple more in different colors. For a size reference, I'm 5'3", 34B and about currently 135-140 pounds and I ordered the Medium for a roomy, loose fit.
