Best Control Knickers!

Right, story is I'm on my 2nd wedding dress after having issues with my first bridal shop and I need control knickers. My new dress is perfect to the waist as there is great support but it pushes everything else down giving me a little pudgey belly so need a knickers that just comes to the waist. I dont want to spend a fortune and its barely noticable but just need a little help.
