Leslie looked stunning - despite only dressing for radio - as she wowed in a chic red jumper with delicate black polka dot detailing to give a funky flare. 

Her slender frame was highlighted further by her skin-tight black trousers and a stunning overcoat which skimmed her calves in length. 

Giving a nod to her A-list status, the stunner held on to a blue Chanel bag with a sack style, trademark quilted detailing and silver chain straps. 

Her honey blonde tresses were worn in a side parting tumbling over her shoulders with the tips a lighter shade than the roots.

Rock polka dots by Prada like Leslie Mann

Dressed for the chilly London weather, Leslie Mann headed to an interview at Global Radio Studios to promote her latest movie Blockers clad in a polka dot sweater, cropped pants and ankle boots.

Her top is by Prada and comes with a sleeveless silhouette and ribbed trim. We can't get enough of that eye catching red hue though and the polka dot motif is a classic look that will never go out of style.

Follow the link at right to NET-A-PORTER where you'll find this same style up for grabs for $840. Then layer it over a button-up blouse or wear it solo with some black skinnies and studded booties to toughen up the look.

And if you don't fancy the designer price tag, we've got several lookalike styles in the gallery below that won't break the bank including this strikingly similar version by Elle that's on sale at Kohl's for only $20.

Leslie plays the role of Julie, a mom dead set on keeping her daughter from losing her virginity at the prom in her new movie.

With the help of two fathers in the same position, played by WWE superstar John Cena and The Mindy Project star Ike Barinholtz, they plan to ruin the trios sex pact.

The children are played by Kathryn Newton, Geraldine Indira Viswanathan, and Gideon Adlan. Gideon is the daughter of comedian Pamela Adlon. The Kay Cannon directed comedy is set to hit the big screen on April 6.
