My girls also have longer torsos - overalls never worked on them

when they were little - which was sad!
I also have a long torso but thankfully women's suits offer that. Do they not realize that those of us with long torsos had them as children too??? They don't magically appear!! lol
My girls are not "skinny-minnies" ... they are solid and the bellies come and go depending on growth spurt time or not. They like the two piece tugless tank from Lands End. It has a longer top and it covers their belly. My one daughter wears a plus size and one a regular as one needs a little more coverage than the other

Thankfully their suits are the same patterns whether regular or plus.
Good luck

p.s You can also buy separates at Lands End which is nice too ... especially in the overstocks section. As well they are 25% off right now (maybe until today??) and free shipping!
