Did anyone actually say that or did you just make it up?
I actually went back to check and someone said turning up your jeans is 1 on a scale of 1 to 10 in dandyism, so I guess they sorta said it but i think you're really stretching it to make an objection here.
FWIW I think upturned jeans are like turnups on dress trousers - a trend or a preference but to cuff is neither more nor less dandyish than not to cuff. I don't think that was aimed at me anyway but I think I'm losing the will to live with this shit so I'm out!
This is a perfect example of the dorkyness, with some going too far on the side. I think you have to be deluded or high on SF cool-aid to think this looks good.
It's just way too far out there.
Cardigan. OK, you've done it, you've gone dandy-ish and got attention. Pretty nice, if everything else is chill.
+ Up-turned jeans. Wow, really looking for some attention.
+ Bow tie. "Oh my god, what's going on. Is he in a play or something? Why's he walking around like that?" <- What everyone is thinking.
I feel bad for bashing but there's good SF and there's misguided SF and you have to quash it before it infects us all.
