Gisele Bündchen shows why she's well-qualified to design a range of undies. She seems to know all about looking her best in her smalls, reported British daily The Sun on Thursday.

The model-turned-designer was at her dazzling best as she posed for underwear company Hope in a matching set of red underwear.

The 31-year-old Brazilian beauty proved she still has the fabulous figure that catapulted her to fame as a teenager. The fashion icon was photographed flaunting her body in a black bra and panties. The supermodel, who is married to NFL quarterback Tom Brady, recently told a French magazine her aims as a designer.

"When I create my collection I imagine sexy pieces but also very classy," she said. "I choose different pieces that I would use in my daily life and also for special occasions. Lingerie can tell a lot about you and your intentions.

"This is a special collection, we've matured the creative process and we are also investing in colors and details that make all the difference. I hope that women like it!"
