This Lace Crop Top is two separate pieces. The outer top is a fancy lace – there is slight give in the mesh, but it is not a stretch lace. Please be sure to double check your bust and waist measurements before ordering. The lining is a light silk with horizontal stretch. The lace top is finished with it’s own trim at the hem – and a silk seam binding around the neck and keyhole. They keyhole back has a one button closure.
