Lingerie brand Wonderbra has launched a new convertible bra called 3 Degrees of Hot.

The bra has a choice of three push-up levels, described by the company as "Hot, Hotter and Sizzlin".

The levels are created by a push up “cookie” system, which consists of three pads that insert into the cup.

It also has a number of strap and hook-and-eye combinations that the firm said result in 100 ways to wear the bra, which will retail for a suggested retail price of US$34.
