I have a real love-hate relationship with the best tummy-control underwear. When it works, it works—smoothing, sculpting, and seamless under jeans, skirts, and wedding-guest dresses. But when it doesn’t, I’m counting the minutes until I can yank it off, whether it’s rolling, digging in, or just plain uncomfortable. The best tummy-control underwear should feel like a second skin, giving you shape and support where you want it without the telltale panty lines or constant need to readjust.
