Could be by Persol (maybe PO2978S Crystal in Havana) or Ray Ban in Tortoise Shell! But it's really difficult to tell!

I think it's RayBan RB2140 902/57. Not sure but!

I think those are it! Looks dead on to me... They weren't Persol's cause they were missing the signature arrow on the sides...

really? but the ray ban signature is missing that's because I thought it can't be a ray ban.

does authentic rayban all got their logo on their lenses?

 

[minababe]

yes all ray ban sunglasses have the white logo.

I don't think they are PERSOL. Lauren's doesn't have something on the sides like the PERSOL ones at your pic.
