Seen this in the tk maxx at chilwell, they had loads of sizes in either black or nude. Also have the Trinny & Susannah magic tummy flattner. I have one of these and paid £30 for it last year, seen these at £7.99 so I bought another. Very comfy for what they are.
With the gut busting, waist slimming upper half, and the discreet thong style knickers lower half, the Trinny and Susannah High Waist Magic Thong combines the best of both worlds. You will get the zero VPL (Visible Panty Line) look of a thong and the belly busting, waist cinching power of a pair of high waisted Magic Knickers. The Trinny and Susannah High Waist Magic Thong is the have-it-both-ways underwear: a seamless, vpl look but with a supportive waist cinching top.
