I am 6ft tall, weigh 180lbs and have an athletic build. The medium size fits very well. The legs are snug as they should be and there's plenty of room for broad shoulders. I wear a tailcoat size 40-42 depending on the manufacturer. I didn't realize the belt had to come that high (close to the navel) but apparently leaving room for layers of clothing is the right thing to do. I am happy with this purchase.
