Tania, could you post a picture of you wearing them? I would say in this case it would be all about the fit, so it's hard to tell from the pic. I'm a fan of widelegs and flares and trousers, and I'm very happy that the trend is back. Having said this, I agree that they do look looser in the thighs than what I'd expect or want, at least for myself. Leaner thighs are more elongating. These ones are a bit on the quirky/vintagey side to my eyes.
But then again, it's all about the fit! If you're tall they may look great.
