A plain turtleneck with one detail worth looking at twice: a row of buttons set at each cuff, running up from the wrist along the sleeve edge. It is the sort of finish you notice when the sleeve is pushed back, and it is the reason this reads as considered rather than basic.

The knit has real stretch, so the slim cut sits close to the body without gripping, and the neck folds over to a comfortable depth instead of standing rigid at the throat. Ribbed cuffs and hem hold the ends in place, which matters on a jumper this close to the skin, because it stays where you put it under a blazer or a coat. Long sleeves and a regular length at the hip make it the layer that goes under everything through autumn and still works alone in a warm room. The narrow shoulder line is what lets a coat sit over it without bunching, and the buttons keep the cuff neat when you fold the sleeve back at your desk.
