I must be beyond help because my first Gen X reaction was, JEANS ARE NOW £325?!?!?!? I remember when forking out £120 for a pair of Paiges was considered lavish. Maybe it's not the style of jeans that dates you, but the maximum price you're willing to pay for a pair...
And in any case, as every fool and Mae West knows, the whole point of flares is to conceal a giant pair of platforms underneath in order to make your legs look longer. Wearing flares with flat trainers (as I think you're meant to do?) now makes everyone look like a Shetland pony. Vive le 1970s, I say.
