I would look at someplace like Lands End. They have good quality suits with decent coverage and they are always having sales. In the mall you can go to a shop like Everything but Water but sometimes I find their choices a bit too trendy.
Swim suit and the young one mentioned in op’s post, reminded me of beer story in link Pappa Pappa Pool Was Cool I hope reader and op bear with my digression here. I hv no knowledge about links in Amazon for the product mentioned.
