B2prity womens Tankini Tankini Set

I'm 5'7 and 234 pounds and have a 42H bust what size wouuld be recommended

Im 5'5", 180lbs, 38b size bra. would a large or xl fit better?

Does it have good coverage over your bottom? I hate when bathing suits have half your cheeks hanging out.

What size should i get if i am 5'2, 134lbs, 34C boobs and also 5 m pregnant? i want to feel comfortable and sexy in the swimsuit without looking huge.
