This Sunday, Katie Holmes takes to the TV as Jackie O., one of history's biggest fashion icons, in the miniseries "The Kennedys." So for this installment of The Weekender, we've put together a ladylike look inspired by the Camelot years.

Style tips:

Trench: Every woman should have a classic trench in her wardrobe. It's the ultimate, versatile spring transition piece. Wear it with punky leather shorts and a tee for an edgy look or, in this case, with a classic shift, for an elegant outfit.

Dress: The shift was a wardrobe staple for Jackie O. This Banana Republic version feels fresh, tapping into spring's lace trend.

Necklace: If traditional pearls feel a little costumey, consider a string with modern details like this one by Alexis Bittar. Strung with brown silk ribbon, it has freeform sterling silver touches.

Sunglasses: Large sunglasses were a Jackie O signature. These TopShop lucite-style shades add a little mod edge.

Watch: The only accessory more famous than her sunglasses was Kennedy's Cartier tank watch. This Bulova watch is a more affordable version of that shape.

Shoes: Round toe flats and pumps were a Kennedy shoe staple. Buying nude-colored flats and pumps help elongate the leg.

Handbag: If Kennedy were around today, she might carry a ladylike bag from Kate Spade. The nude patent leather is a great fit for spring, pairing well with the season's warm neutrals as well as its focus on color blocking.
