Avengers hit the big screen and we've got all the details on Sexy Scarlett Johansson's catsuit!

Johansson who plays Black Widow in the film is a blonde bombshell in real life-but to play the part in this action packed blockbuster, she traded in the blonde for some fiery red locks.

The actress spills to InStyle the moment she really started to embrace her character was when her blonde transformed to Red! She said quote, 'I love that the red hair is associated with this character. It's now kind of her trademark.'

ScarJo's put on her glam for the red-carpet promotion of the film wearing some amazing designers and elegant dresses-but, that cat suit is quite the statement piece.

Johansson said the first time she tried it on, she was doing high kicks the whole time and she immediately told the wardrobe department that they needed to reinforce the seams, because her suit had to be extra tough!

The film's director, Joss Whedon loved the catsuit on Scarlett-and while it's a tough piece for a gritty character, Whedon said it still had to be gorgeous. He said, quote, 'You want her to look as good as possible, but you also want to believe that that's the best thing she could be wearing.'

And it looks like it is the best thing she could be wearing-it hugs her in all the right places, while still giving her character the edge she deserves. .
