After Losing 100 Pounds, This Woman Wore a Bikini For the Very First Time — On National TV!

Swimsuit season is here!

And when a viewer named Tacara -- who recently lost 100 pounds (!) -- came to us for help in finding the perfect bathing suit for her new body, we knew exactly who to call:

Former Sports Illustrated Swimsuit cover girl Paulina Porizkova, of course!

"She's never worn a bikini in her life," Paulina says of Tacara. "Ever."

But, of course, the supermodel knew just what to do to find one that Tacara would feel comfortable in.

Watch the video above to see how fabulous and confident Tacara looks in her first-ever bikini!

(She was BEAMING.)

Paulina's swimsuit shopping secret? Buy separates instead of forcing your body to fit the top AND bottom of one particular suit.

Yes, yes and YES.

And the model -- who recently posed for Sports Illustrated Swimsuit for the 7th time -- didn’t stop there.

She also used her expertise to help two other viewers find the best swimsuits for their bodies.
