this type of top is my absolute wardrobe staple as i have phobia of exposing my horrible arms and chest, plus i live in scotland so it's freezing all the time! So i almost always layer and wear long sleeved tops under little t-shirts, dresses etc.used to get them from m&s,nice smooth fabric, v thin but in a nice way, they have discontinued them now, and the ones i have are almost washed away to nothing! Anyone any recommendations? Been looking with no success!
