Swimsuit advice..what do you think?

So I need a maternity suit BUT the selection available is limited as I am sure y'all know! it is maddening! so I am debating this one which is plus size but may work if I order one or 2 sizes larger. (prepregnancu I tend to be a solid 16/18, so Im thinking maybe a 18/20 or 22/24 bc I can adjust the bust with my machine if Needed) it's a one pc suit but I like that it has a fairly long skirt on it and its not.halter bc those never stay up.on my back and pull at my neck. these straps seem solid and the back doesn't scoop low. Most 2 pc Tankinis have bottoms that roll down and rarely sit well on my fluffy figure... anyone have advice or found something flattering? Online ordering makes me nervous BUt i cant find anytbing locally that not going to ruun 75.+
