I recommend suits by "It Figures". They sell them at QVC, some Fashion Bug Plus stores, but you can also get them on Ebay for cheaper. (They are expensive suits-but WORTH IT.)
They have them for various figure problems-big tummy, heavy hips/legs, big bust...
They are very well made, and also come in regular sizes, as well as plus sizes. I think this is great-because even when I lose a lot of weight and am near goal-I still won't wear a string bikini because I have a lot of stretch marks on my hips and upper thighs from my pregnancies. I like the sarong bottomed ones, swimdresses, and skortinis. (It Figures! Has skortinis, which are basically like a tankini swimsuit-a 2 piece tank top and shorts-except they are cut looser like regular shorts, rather than the little skin tight boy shorts. They are VERY flattering, and would cover up your apron nicely.
Here is a link to their suits-please click on one of their "skortini" styles. Be sure when you look at the link, to click on the "More View" link under the suit picture. It will show a woman (and not a stick thin model) actually wearing it.

If you go through their suits, you will also notice that their shortinis, skirtinis (2 piece tankinis with a SKIRT bottom), sarong suits, and swimdresses are cut a tad longer and nicer than ones that you buy at Wal-Mart. They are very flattering.
If you like them-go on Ebay and see if you can find one at a cheaper price!
