My only regret is I didn’t buy all 4 colors. I only bought 3 colors in black, navy and gray, and with the 15% off discount I should have just bought all 4 colors. I am 5’3 and 135 lbs., bust size is 36 inches. After carefully reading all of the reviews (Thank You Ladies!!!), I decided to purchase the shirts in a Large. I like a roomy, relaxed fit and I must say I am so happy with my decision. I normally wear a size medium comfortably and even a lot of my size small t-shirts still fit me just fine but when I exercise, I don’t like things hugging and being too conformed to my body. The length is perfect. It provides just enough room without being oversized. Overall shape is perfect and just what I was going for. And even if they shrank a little bit, I would not be mad. The shirts are not see-through. The material is superb! So happy I found this company. I searched endlessly trying to find 100% wool shirts Made in the USA. This company checks all of the boxes on price, material and manufacturing. So happy with my purchase. I look forward to buying more of your products.
