Find jeans that are comfortable and that make, what I affectionately refer to as the muffin top, look as small as possible. Some times I like the low rise better...but I purchased some extra long undershirts (from layersclothing.com) to wear under my tops to my rear doesn't hang out...and a good belt too (The wider belt, the better for me). Other times I prefer to wear a mid-rise jean but make sure the fit is "relaxed fit." My favorite jean store is Buckle. They have their own brand BKE, about $75 for one pair. This is spendy but well worth the money. I have two pairs of their jeans which I'd much prefer over having 3-4 jeans that don't fit right. Plus they're high-quality with cool back pocket patterns. The KATE stye is mid-rise and relaxed fit, if you want to check it out.
Once you have this part down, the other key is to find shirts that are flattering, that hide that part of your body. I love shirts with empire waists that are loose-fitting around the waist, and shirts with a wide band around the hips, then loose above. to create a flowing look (while hiding the middle section).
Hope this helps! Good luck!
