i don't cut, but i have a niece who does. so, i'm very sympathetic to the problem of summer and bare arms. recently, i found a blouse, for myself, that is made of a very thin and pretty cotton. it is teal blue and it is cool to wear, in hot weather. it has three-quarter length sleeves. i know that is such a rarity, but you might ask at some of your favourite stores. call them...don't go in.......and if you can sew, get a pattern and make yourself something really pretty...cause you deserve it, first, and then, because it covers your arms. xoxo pat
