For some girls, no matter how skinny then are, a pair of low-rise jeans means one thing: muffin top. Enter Yummie Tummie, new "shapewear" that is designed to smooth out all of us. Simply described, it's a tank top that has cotton on the top and bottom but a fiber blend in the middle to suck in that tummy. Creator Heather Thomson has a slew of celeb patrons, including Oprah, J Lo, Beyonce and Carrie Underwood. This weekend, Thomson will be in St. Petersburg to peddle Yummie Tummie on HSN. She'll also share style tips today from 2 p.m. to 5 p.m. at Paradise Island Boutique, 3316 S West Shore Blvd., Tampa. WFLA-Ch. 8 will be there filming a TV feature, so get your muffin top camera-ready if you're planning to stop by.
