joggers leggings trackies

[humblesims]

I'm fat. Middle aged. I look like a dinner lady.
I walk a lot but I need to wear more suitable stuff and want to walk faster and (argh maybe jog one day).
I want some thing which is as comfortable as joggers but NOT elasticated bunchy waist (I carry all my weight on my fat tummy) but is not as clingy and revealing as leggings.
What am I looking for.
I know this sounds like a riddle but honestly I'm clueless.

Would something like these do? Small bit of elastic at the back only for a bit of stretch.

Or these. Not bunched up elastic. I have some (old) similar ones from next & the waist band sits flat but has stretch

I would just go for leggings in a dark colour with a longer top but choose thicker leggings so they hold you in a bit - Sweaty Betty ruched leggings are great.
