I'm glad it's not just me. I agree with you @Softoprider and @Nofixedabodewell - I don't think jumpsuits look flattering if you have a big belly.
I'm a similar shape - big boobs and I carry my weight on my tummy. I'm quite tall with long legs so in theory a jumpsuit should be flattering on me. Without exception, I look like a sack of wriggling pigs.
If you're curvy, jumpsuits can look amazing and I agree with the right cut, a jumpsuit can be stunning on a bigger figure. But curvy isn't the same as big tummy - that's a very specific area that I've never seen look good in a jumpsuit.
Some don't look terrible when you're standing up - but as soon as you sit down, the tummy area with all its pudginess is accentuated. It's not flattering whatsoever - and there's no cut that's going to save that.
But just to be clear, I'm not saying if you have a big tummy you shouldn't wear a jumpsuit. If you feel comfortable and confident, then all power to you. Wonderful.
I'm not especially body conscious but the OP asks for a jumpsuit that "suits" big boobs and a tummy, and I'm just saying that I don't think there are any that do. Lots of lovely jumpsuits posted here - not a single one so far that would be flattering to a bigger tummy. I looked at them all excitedly hoping to find a magic jumpsuit that I could wear - but there's nothing. If you're the slightest bit self-conscious about that tummy bulge (which we all know is worse when sat down) - then I would say a dress or trousers and top would be far more "suitable".
