JINXUEER Women's Plus Size Swim Skirt High Waisted Swimsuit Bottoms Swimwear Board paired Bikini Tankinis (Blue, 20)

If I’m 5’3 210 what size would you suggest I get?

What is length of skirt?

Is it cholrine resistant?

I'm a very large (265lbs), bottom heavy & about 5 '7.5" women, i'm not sure about what size skirt to get? i think an 28 but not sure.
