UMMISS Womens Underwear,Cotton High Waist Underwear for Women Full Coverage Soft Comfortable Briefs Panty Multipack, Black-grey-total 5 Pack, Large

Q: do these help with incontinence?

No, they do not. I will say they are not very well made at the waist band and come apart. I do not recommend.

Q: What size would you recommend if your pants are size 16?

I wear 12 to 14 size pants and I bought large. They are a perfect fit! I would say XL maybe? I will add these are the most comfortable panties I've had in a long while! I love the way they come up high on the waist so that even if my pants slide down a bit when I sit or bend the panties stay in place.
