Cos advert stated as fits size S & M n did not state is see thru . Am surprised is very thin the material so look thru to see if I can accept it but really can't.Have also see the dress in front of mirror n is really too big for me . Just cos u insist the indicated size L is for S n M does not mean it really the case and u r not the manufacturer. Ur advert also state is free size,fits Usual S & M nt size L. I even specially rush down earlier to meet u at your request. Saw running threads too ...
