Finally an optimal T-shirt that is great both in a shirt and under a sweater or cardigan. It fits tightly with good stretch property, nice and long and has a clean, narrow collar. After the first wash, it also seems fairly stable in shape. Here you will find this kind Shirts rarely. Either vests are offered, most of which are too thin and the purchase of a German premium brand also expensive. T-shirts are my turn too far or too short and have wide cuffs at the neck.
