| Bra rides up during movement | Underband width, pressure, elastic recovery, or body length is not balanced | Underband construction, elastic direction, body length, fabric recovery, size grading | Adjust underband width, elastic tension, or body length before sample approval |
| Support feels weak during training | Support level, fabric power, strap structure, or underband hold is not strong enough | Fabric recovery, strap load, underband pressure, cup coverage, activity level | Increase support through fabric, strap, underband, or coverage adjustment |
| Straps dig into shoulders | Strap width, strap angle, back tension, or support load is not balanced | Strap width, stretch, angle, shoulder pressure, back structure | Revise strap width, strap angle, or back structure during sample fitting |
| Pads shift after washing | Pad pocket shape, opening position, lining tension, or pad size is not suitable | Pad pocket, pad thickness, lining fabric, opening position, wash behavior | Adjust pad pocket shape, opening position, or pad specification |
| Cup area feels empty | Cup shape, neckline, coverage, padding, or size grading does not match the body shape | Cup depth, neckline, side coverage, pad shape, size grading | Revise cup coverage, neckline depth, padding direction, or grading |
| Side coverage is not enough | Armhole curve, side panel height, neckline, or strap position is too open | Armhole shape, side panel height, coverage, strap position, size range | Increase side coverage or adjust armhole curve before bulk approval |
| Compression feels uncomfortable | Fabric power, underband pressure, pattern tension, or lining support is too strong | Fabric stretch, support target, underband pressure, neckline, lining, fit sample | Reduce pressure through fabric choice, pattern adjustment, or underband review |
| Lining feels rough or hot | Lining fabric, mesh, seam placement, or fabric thickness is not suitable for skin contact | Lining handfeel, breathability, seam bulk, mesh placement, skin contact area | Review lining fabric, mesh placement, or internal seam construction |
| Front zipper feels unstable | Zipper quality, inner guard, top stop, neckline tension, or underband hold is not balanced | Zipper, inner guard, top stop, neckline, underband, stretch area | Revise zipper structure, add comfort guard, or adjust neckline tension |
| Matching set color does not align | Top and bottom fabric, dye lot, lining shade, finishing, or material base may differ | Fabric source, dye lot, shell shade, lining shade, finish, set coordination | Confirm set shade under the same light and approval standard before cutting |
| 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 support feels different from approved sample | Fabric approval, elastic tension, padding, lining, PPS, or QC checkpoints were not locked clearly | Approved sample, bulk fabric, elastic, padding, lining, measurements, sewing, QC standard | Align PPS, measurement spec, fabric, elastic, padding, and QC checkpoints before bulk |
