If you're looking for a cheap look a like you should choose the ones from a couple pages back - there's a link. Otherwise a decent replica would be the actual ray-bans, one person here has opted to have actual ruby quartz authentic lenses
The costume department custom made some dark red mirrored lenses. Did whoever get the actual lenses through oordeing them from Ray-Bans or another company?
No idea, you'd have to ask him. I'm sure there are photos of him wearing them a few pages back, maybe a good idea of what it looks like, he also said you can't see too well in them either which is a shame
