Tried on a few pairs in-store and love the look and feel of the Ray-Ban Aviators. However, when it came time to order, I was stumped with the sizing. One time the clerk told me that the sizing is most likely "medium."
Online however, measurements are listed as:
55mm
58mm
62mm
Exactly which of these measurements correspond to small, medium, large?
Would love some help and could possibly make this into a guide of some sort as google results in no finds of "Ray-Ban Aviator sizing" etc.
TIA
P.S.
For the record, if this has been asked/posted please forgive me for not using the search button.
