WHAT I'M STUCK ON

Aiight so I'm way to shy to walk up to a stranger and ask, "Yo excuse me, but where did you get your *clothing item* from", but damn Jay-z been sited a vast amount of times publicly in these shades, from the DOA video, MTV awards and interviews... and i been stuck on the Ray Ban warfer shades for a good 5 years now, but these shades came in and i forgot all about the Ray Ban jawns! And i have the slightest idea who these shades are made by, dont really care, i jus need to kno where i can purchase mines???? That aint askin to much is it??? I cant call it
