Basic of excellence, take it with long sleeves during the winter of course. There are many varieties of t-shirts: V-shaped flights, more or less open, patterns in drawing and writing ... I advise you to favor a round neck, easier to match, and take it in a light color. The t-shirt is one of the few pieces that can be selected in white without risking mistakes. Do not hesitate also pastel colors (sand, taupe, metal, sky blue ...).
