Shaping leggings?

[NYresolutions23]

I wear leggings 90 percent of the time due to varicose veins and jeans hurt my legs.
However after 4 pregnancies i have a saggy lower tummy.
Size 14/16
I am. Trying to lose weight but I know it will not help the lol stretched saggy belly /skin.

So think some magic leggings may help.. And they'd have to be pretty magical

Sweaty Betty power leggings are miraculous. Grab them whilst in the sales. V good value for money.

Just looked. They're out of my price range unfortunately.
