Many times, the stitching tells it all. Authentic dresses will always have smooth, uniform stitches because they are carefully made and checked for quality. Any dress that doesn’t make the cut isn’t allowed to be sent out for sale. Corset Dresses should have perfect fitting and detailing, especially if it’s supposed to be your perfect size.
Check the stitching across the necklines, seams, hems, and pockets and make sure that they are all neat, straight, and have equal lengths. Any roughness or mistake shows that they were hurriedly stitched or not made by professionals, which is a tell-tale sign of fakeness.
When dealing with lace or Sequin Dresses, pay attention to things like lace pattern symmetry and intricate beading reflective of the standards of the clothing brand you’re purchasing.
