Under-skirt things to prevent chafing, rubbing, the thigh skin catching?

I had a wedding to go to. I didn’t want to wear support pantyhose. And after many minutes of trying to get Spanx “shorts” in my size up to my belly, but unable to get them past, I got so upset I tore them off & threw them in the corner. So I put on the thigh bands I bought just in case. They didn’t work so well. They started to roll. So, I’m getting rid of them, too.

Do you prefer silky pantaloons? Or stretchy yoga-style? Or what? What brand? What length? What style?

I just ordered both. Length: almost to the knees. But I’m open to other suggestions.

I’m just worried about the stretchy yoga-style rolling up or getting baggy & working upwards, & the waist rolling down.

I like my maxis. I can wear my “rubber slippers” instead of heals because of swelling that began many years after pregnancy. Even wides won’t fit at times. I figured I can also forgo the support pantyhose. It’s all about comfort. I grew up a Tomboy fighting against skirts & dresses, pantyhose & tights, & heels. Give me jeans, Bermudas, & capris, Crocs & flip-flops! lol
