Shop nowA square neckline is unforgiving of a bad pattern: cut it too narrow and it reads as a boat neck, too wide and the straps slide. QINSEN uses one block across the whole line, which is why the tank, the bodysuit and the mini dress in this collection all sit at the same point on the shoulder. It is also the reason these pieces layer with each other without three necklines fighting for attention.
