Blake Lively just wore dress made almost entirely out of underwear

And it’s still so classy. How you do, Blake?!

Blake Lively has been making the rounds doing her press tour for A Simple Favour (her new movie with Anna Kendrick) and during the tour she has only been spotted sporting a wide range of three-piece suits.

While some looks may have looked more at home at a 1920s golf luncheon, Blake being Blake managed to look goddamn gorgeous in every single one.

However, it seems that Blake is now ready to ditch the suit and has stepped out for the first time in months in something different.

And while most when straying from their fashion norm edge just a little outside their comfort zone, Blake decided to do the opposite and went nearly-naked for her non-suit debut.

Blake walked the red carpet before the Christian Dior show during Paris Fashion Week wearing a Dior (of course) dress that looked like it was constructed almost entirely out of underwear.

This is potentially Blake Lively's most naked dress to date and it featured a practically sheer corset bodes with an embellished sheer slip draped over it and was topped off with a faux hoopskirt — giving us all a little history lesson in ye old undergarments.

Blake obviously looked bloody great and seemed chuffed to be out of her three-piece rut.
