Granny panties and corsets? Not in Bethenny Frankel’s closet! The reality star is making undergarments sexy with her line of problem-solving shapewear for her growing Skinnygirl brand. According to WWD, the collection of tummy-smoothing and bulge-concealing shapewear will include sleek, seamless-looking camis, tanks, half-slips, high-waisted briefs and leggings, all with sexy designs and lace detailing. “The line ranges from tank tops in black or beige to my signature color, red, which is a confidence color, and a little daring, but not white because it can make anyone look bigger,” Frankel tells WWD of the collection, which will go head to head with Real Housewives of New York frenemy Jill Zarin’s line of figure fixers Squeez. But Frankel’s collection includes much more than just panty-smoothing pieces: look for what she calls “lazy lingerie” and a sexy apron with a bra, which she claims is “a fun item with a little skirt you might wear for Valentine’s Day to wake up … and fix your husband breakfast in.” Items will sell for $20-$40 and be available mid-March on Skinnygirlshapers.com.
