Design details like ruching or shirring can be deceptively slimming on the body. Shirring refers to tightly woven gathers in the fabric, and it not only holds you in, but it is so-called “figure flattery magic,” according to Krock. It hides any traces of bulging, while hugging the waist and curves. Ruching, characterized by draped and gathered fabric, is another secret weapon to rely on, and it doesn’t have to be allover either. If you have a tummy, look for ruching across the midsection. Princess seams will also provide structure to a suit, giving you an hourglass figure, while concealing imperfections. A small, allover print can also help to camouflage a full bust or tummy.
