Yes, skinnies outline my natural shape but I expect my clothes to work harder than that. The skinnies of around ten years ago weren't so bad - they were more relaxed in the leg and weren't stuffed with lycra. But the current crop just leave me nowhere to hide.
Of course flares/bootcuts aren't universally flattering but at least they come in different shapes and cuts so I can play around with proportion and width. And they take the focus away from my thighs. It's all smoke and mirrors but that's what flattering clothes are meant to do.
Having said all that, I'm not rushing back to them as I don't wear heels and I don't think they work nearly so with flats. Plus they're useless in the rain. At the moment I'm back in some old straightlegs and some relaxed skinnies of yesteryear. (This is why I will never have a capsule wardrobe!)
I think this is a good time for jeans as there is a choice in the shops and it probably won't last so we should enjoy it.
