Seems more to do with weight/bodyshape than age, going off these comments.
I am another, never liked skinny jeans but loving new styles of trousers and jeans right now, so relaxed and an exciting new silhouette (it's been too long!).
Jeans don't restrict if they're correctly sized and not a tight style. Getting skinny jeans on and off was hellish for me at 7st 10 (5'5). Sweaty Betty leggings are a pain in the arse for that, too, but do look decent on.
We have a lot more choice now, my faves are combats, both cuffed and wide legged. Soft loose fit cords with a mid rise are great too for winter. No matter how slim we might be, skinny, tight or restrictive clothes are uncomfortable on the skin, soft tissue, the gut, bowels, and knee hinges.
I say this a someone who suits dresses but never wears them as I always feel like they're too thin, unlined and crazily patterned. If they start making simple, well made dresses in good fabrics that don't look like small tents or stiff office wear I would be happy to give it a go!
