Jackson Lee / Splash NewsSienna Miller and Marlowe are the sweetest shopping buddies!
The 31-year-old fashionista and her adorable 7-month-old daughter were snapped on the streets of NYC after shopping in SoHo Tuesday afternoon.
Tom Sturridge's fiancée looked hipster chic in boyfriend jeans, a gray sweater and leopard flats, carrying her best accessory—her darling daughter—in a baby sling as she hailed a cab.
The blond beauty's bundle of joy practically killed us with cuteness, wearing her dark brown hair in a mini ponytail and sporting a puffy pink onesie to keep warm in the crisp New York weather.
Sienna quickly became one of the most stylish Hollywood moms after welcoming her first child with her hubby-to-be in July.
And from the looks of the precious pair, the trendy mother is already passing down her impeccable taste to her little cutie pie!
