I recently purchased 5 Ralph Lauren Polo's on E-bay by seller louie lulu3 The shirts were fake here are the easy ways to tell:
1. The workmanship
2. The tags (made in USA) shirts are made in Vietnam, India, China, Peru, etc.. but I have yet to purchase a real one made in USA
3/ The sizes are all different and a XXL is about a medium
4. Read the mission tag. The one I had contained misspelled words and the wrong words utilized
5/ The buttons had PIOI instead of polo and a real shirt has buttons that don't contain any lettering.
6. The embroidery of the Polo guy on horse is not precise or intricate
7. Button holes aren't precise and open partially sewn shut.
