Fitting clothes that are too big can be done through several non-sewing methods. One approach is using elastic bands or belts to cinch in the waist of oversized tops or pants, creating a more tailored silhouette. Clothes clips or fashion tape can also temporarily adjust the fit of garments by securing excess fabric in less visible areas. For those looking for a more permanent solution, clothing can be shrunk by washing in hot water or drying on high heat, though this method should be used cautiously to avoid over-shrinking or damaging the fabric.
