I'll also recommend a freediving suit. The two piece, open-cell interior is by far the best fit and warmest of suits I have tried over the years. They are super stretchy because they don't have nylon on the inside, not because it is some crappy "super stretch" neoprene that feels great in the dressing room and is horrible once you get a few dives on it.
I currently have a Mako suit, which has been a solid performer, but have had a 4 other freediving suits prior. I'm not a petite woman, so I can't comment on brand specific sizing for you, but they will inherently have a more forgiving fit than any one piece will. And custom is always an option, just make sure you get yamamoto rubber if you go that route, it'll last much longer. The custom brands I know of are Elios, Oceaneer, and Deep Thought.
