I will never go sleeveless again. I am fit and have worked out since my 30's but age and heredity have taken a toll on my upper arms. Also, had a water skiing accident when I was a kid and now that the fatty layer is not as firm, the muscle really looks distorted. I saw that in the mirror one day and could not for the life of me figure out what caused it. It finally dawned on me one day - of course I was only 10 when I fell on the skis. My arm got tangled in the tow rope and dragged me quite a distance before my Dad even noticed that I had fallen. So, anyway, I dread shopping, even for summer tops and tees anymore. Have to have 3/4 or elbow length sleeves - period....
