| Waistband rolls down during movement | Waistband height, pressure, recovery, front rise, or back rise is not balanced | Waistband construction, elastic direction, rise, fabric recovery, size grading | Adjust waistband height, pressure, elastic, or rise before approving sample |
| Leggings feel soft but become loose after wear | Fabric recovery, knit structure, spandex ratio, or pattern tension is not strong enough | Stretch recovery, fabric composition, GSM, wearing tension, sample after repeated stretch | Retest recovery and adjust fabric or pattern tension |
| Squat coverage is not stable | Fabric density, GSM, color, stretch behavior, or size grading may not support opacity | Light color behavior, fabric stretch under tension, GSM, density, size range | Check opacity under stretch before bulk fabric approval |
| Compression feels too tight | Compression level, pattern tension, waistband pressure, or size grading is too aggressive | Compression target, fabric power, hip curve, rise, waistband pressure | Reduce pressure through fabric choice, pattern adjustment, or grading review |
| Side pocket pulls or gaps | Pocket depth, opening angle, side seam stress, or fabric recovery is not balanced | Pocket placement, phone weight, side seam, fabric tension, opening angle | Test pocket with phone weight and movement before approval |
| Crotch area feels uncomfortable | Gusset shape, crotch curve, inner seam, or fabric stretch may not match activity use | Gusset shape, crotch fit, inseam, seam bulk, anti-chafe comfort | Adjust gusset shape, seam position, or crotch curve |
| Inner seam causes friction | Stitch type, seam bulk, fabric thickness, or seam placement is not suitable | Flatlock option, seam allowance, fabric thickness, inner-thigh movement | Review low-bulk seam or adjust seam placement |
| Leggings look good flat but fit poorly on body | Pattern tension, hip curve, rise, inseam, or ankle opening was not reviewed on body | Fit sample, body curve, rise, inseam, ankle opening, movement comfort | Fit test on body and revise pattern before production |
| Light colors look different in bulk | Lab dip, dye lot, fabric base, stretch behavior, or finishing may differ | Lab dip, bulk fabric shade, light-color opacity, color under stretch | Approve lab dip and bulk fabric shade before cutting |
| Matching set color does not align | Top and bottom fabric, dye lot, finishing, or material base may differ | Fabric source, dye lot, shade matching, finish, set coordination | Confirm set shade under the same light and approval standard |
| Logo cracks or peels after stretch | Logo method, placement, heat pressure, fabric stretch, or washing behavior is not suitable | Heat transfer method, stretch zone, wash direction, logo size, placement | Test logo on stretch area before confirming bulk decoration |
| Bulk feels different from approved sample | Fabric approval, PPS, measurement tolerance, finishing, or QC checkpoints were not locked clearly | Approved sample, bulk fabric, measurements, sewing, finishing, QC standard | Align PPS, measurement spec, fabric standard, and QC checkpoints before bulk |
