But the design is so classic that it's super easy to find without resorting to dropping major cash for the Tom Ford original!

After working hard to lose so much weight, the contestants of this season's The Biggest Loser: Couples will soon be getting their celebrity-styled makeovers.
And we use the term "celebrity" lightly. Hah.
Set to style the couples will be singer Ashanti and helping her will be Shear Genius judge, Jonathan Antin.
The episode, which airs on May 4th, will feature each of the remaining six contestants getting $1,000 to go on a shopping spree at their favorite store.
Ashanti will be on hand to help them while Antin will style their hair before their big reveal.
Hopefully they don't all end up dressing like Ashanti!
