The actress was seen leaving her office in Beverly Hills, and she was her own best advert in a piece from her Draper James collection.

Reese showed off her long and slender legs in a thigh-grazing blue and white printed skirt that retails for $225, which she wore with a long-sleeved white top.

The mother-of-three gave her petite frame a boost in a pair of yellow heeled pumps, which coordinated well with her yellow and white handbag.

Reese had her blonde locks styled straight, and also wore several pieces of gold jewellery and a pair of retro pale pink wayfarer sunglasses.

The Wild star, who was talking on the phone while leaving the building, finished off her look with rosy blusher and bold red lipstick.

Reese celebrated in style ahead of her 40th birthday on Tuesday, throwing a star-studded party on Sunday night at Warwick in Hollywood.

Get femme like Reese in a navy pleated skirt

Reese Witherspoon wears a lot of labels, but clearly her favorite is her own mark, Draper James. Literally spotted in her own designs several times per week, the savvy business woman knows the paps will snap her in her own designs, women will want to emulate her and the sales will rack up. Okay, so everybody knows what's up.

That said, the pieces look fantastic on Reese and they strike the Southern feminine note she's going after. Take this skirt, for example. The navy color and white abstract print along with the diagonal pleating is ultra charming as is the over-the-knee length.
