Oh I thought it was a. It of a geek chic ironic thing re: 'mom's jeans. Either way I have several pairs (different colours) and love them (am 30). They're comfy and make almost any tucked in -short or jumper look cool and a bit 90's, which I think is more of the moment as a silhouette than skinnies. Look cool with heels as well!
What I will say is that I think they'd look better on me if I had more of an arse and hips, I'm fairly slim and they look fine, but I think they look most flattering on those with a larger backside and small waist/flatter stomach as they accentuate that. As I'm not dressing to highlight my figure I don't care but I do think that's the case. If anything they've mostly been a revelation and lesson in the fact that I don't 'need' to accentuate my figure when I dress/why was a before and for whom when it boils down to it/there are other ways to feel good in what you wear. Each to their own though, no trend is for everyone is it!
