Mad Men star Kiernan Shipka works a casual look in a grey sweater and dark wash jeans

She may only be 15, but Kiernan Shipka has already established her keen eye for fashion.

But the Mad Men actress's skills don't only extend to red carpets, as she was spotted working a casual cool look on Sunday.

She wore a fitted grey sweater, cuffed blue jeans, and a pair of shiny, black oxfords as she strolled around Los Angeles. 

Kiernan looked effortless in a fitted grey sweater, which she coupled with a pair of dark wash denim jeans.

The Flowers in the Attic actress had her jeans cuffed, and she coupled those with a pair of shiny, black oxford shoes.

Her short blonde locks were pulled up into a bun on the top of her head, with a few short wisps of hair falling around her face. 

Kiernan - who plays Don Draper's daughter Sally in the AMC series - accessorized with a small, gold necklace, and was spotted sporting a small, grey, leather cross body purse.

The actress's nails were painted grey, which coordinated with her sweater, and she carried a pair of sunglasses with both a tortoiseshell and lime green design.

She seemed to keep her makeup simple for the outing, but did appear to be wearing a light, peach lipstick.

Most recently Kiernan was spotted wearing a floral ensemble with a pair of strappy black heels at the AFI Awards, which took place on January 9 in Beverly Hills.

Her Mad Man co-stars Elizabeth Moss and Jessica Pare were also in attendance, because their AMC program was being honored at the ceremony.

Mad Men is heading into its final season this year - the second half of the show's seventh season - with the first episode premiering April 5, 2015.
