I searched high and low, comparing various options, before selecting this bolero. It has just the right amount of coverage without being too bulky or warm. This standard size also worked perfectly for me. I have broad 17-inch shoulders and wear about a US size 10 (somewhere between M/L), and I was able to move my arms comfortably with a bit of room to spare. I was concerned from the model photos that the color would lean more navy or off-black, but I am happy to confirm that it is a true black in person. Excellent quality, and delivery to the United States was quick as well. Thank you!
