What looked great on SmQ now is worn in a very different context. I normally see Persols on overweight white dudes who think they're top shit because they're wearing McQueen's glasses. Many consider it naff to wear a big brand across my shirt, or to wear a big sparkly gold branded watch, or to wear shoes with big branded buckles on them, or to own luxury-eurotrash-patterned leather goods or a big Hermes H belt. Why is this different with glasses?
Besides, would SmQ have approved of paying $400 for designer sunnies?
Likewise I kind of agree with you. Persol are very distinctive glasses and I can see how you could call some models fussy or overdesigned. I would imagine it may be a little awkward if you walk into the same room and another chap is wearing the same pair of Steve McQueen specials you are. Then again, Persol make some excellent frames, not all of which have "Steve McQueen" written on them (that is, frankly, pretty try hard).
