Shop nowThis is the busiest corner of the QINSEN catalogue, and the one where the fit block matters most. Crop lengths are cut to hit either at the natural waist or two inches above it — never in the ambiguous middle — so a high-rise legging meets the hem cleanly. The ribbed tanks use a heavier gauge than the seamless ones and hold a straight line under a blazer; the halter and square-neck crops are the pieces the brand is actually known for. Several styles carry a shelf bra, which changes the sizing advice: go by underbust rather than by the number you wear in a tee.
