In order to investigate dynamic drape of woven fabric, vibrational property of weave was analysed theoretically and experimentally. The motion of weave was considered to be shear deformation and the shear vibrational property was analysed using differential equation. Vibration tester, which was modified KES-LABOMODEL shear tester, was used to examine the motion of the weave. It was shown that weave with buckling like sine wave (buckled-shaped weave) was considered to be equivalent to plate-shaped weave by some correction of weave characteristics such as shear stiffness and weave mass. Women's thin dress fabrics were examined their vibrational properties and their amplitude angles of vibration decreased linearly with time. This means that their shear vibration damp by frictional effect between fibres and/or between warp and weft yarns in the weave and that viscostic effect in the weave can be neglected in the range observed. Viscostic effect of air resistance is also neglected when the length of weave is small (smaller than 0.1 m), but it becomes distinct if the length is large (larger than 0.5 m).The amplitude damping angle is in proportion to 2HG
o/G
o which are characteristic values of weave shear property measured by KESF system.
