Reese Witherspoon is her own best advert as she strikes pin-up pose in swimsuit from her brand

Reese Witherspoon fired up her Instagram page this Wednesday to plug her longtime clothing line Draper James. 

The 46-year-old Oscar winner brought back the vibes of the 1950s bathing beauty pinup posters as she struck a pose in a swimsuit from her line.

She was plugging a collaboration between her brand and Lands’ End and slipped herself into a $114.95 swimsuit from the collection.

Reese perched herself on as surfboard while wearing a elegant polka-dot one piece with a color stream going from sky blue to navy. 

Letting her trademark blonde hair tumble free in luxurious waves over her shoulders, she sharpened her unmistakable features with makeup.

Reese arced her shapely legs to show them off to full advantage, dipping her feet in what looked like sandy water in the shallows at the beach.

‘If “vacation” were a swimsuit,’ the Big Little Lies star wrote in the caption for the benefit of her whopping 28 million followers.

Her upcoming movie releases include the romantic comedy Your Place Or Mine, the directorial debut of The Devil Wears Prada screenwriter Aline Brosh McKenna. 

Way back in 2015 she was attached to star in a live-action Disney movie about Tinker Bell, but the project is still in development.

She will also be returning to her beloved Legally Blonde character Elle Woods for a third movie in the franchise.

The original film came out in 2001 and its sequel, subtitled Red, White And Blonde, came out nearly two decades ago in 2003.

Mindy Kaling, who is co-writing the screenplay with Brooklyn Nine-Nine alum Dan Goor, insisted this year that they were being careful of the series’ legacy.

‘We don’t want to be responsible for ruining what’s basically Reese’s Avengers franchise,’ Mindy quipped to Time in March.

On the personal front, Reese is married to talent agent Jim Toth, with whom she shares her nine-year-old son Tennessee, named after the state where she grew up.

She shares her two older children – Ava, 22, and Deacon, 18 – with her sizzling first husband Ryan Phillippe, whom she starred with in the cult classic Cruel Intentions.
