Sienna Miller Made Her Post-Baby Debut in the Ultimate Indie Sleaze Outfit Formula

Sienna Miller isn't just a regular mom; she's a cool mom. Case in point? She made her postpartum debut while sitting front row at the Chloé fall-winter runway show during Paris Fashion Week.

On Thursday morning, the actress stepped out officially for the first time since welcoming her second child, a baby girl, with her boyfriend, Oli Green, back in January. Sienna is also a mom to an 11-year-old daughter named Marlowe, whom she shares with her ex Tom Sturridge. For the occasion, she exuded cool mom vibes in an oversized black leather bomber jacket that was zipped all the way up and featured a ribbed knit lining. Underneath, she wore a contrasting white slip dress with a lace-trimmed midi hemline and added a pair of extreme wedge sandals to her look, as well as a black handbag and square-shaped sunglasses. 

Miller wore her blonde hair down in her signature boho waves with a middle part and opted for a no-makeup makeup look with a pale pink lip and rosy cheeks.  

Back in December, Sienna spoke with Vogue about becoming a mom again later in life. "I'd love to get to a point where I didn't feel the need to make a joke of my being older and having a baby," she told the outlet, adding, "To show I'm in on the joke." 

The Anatomy of a Scandal star also commented on her iconic belly-baring look at Vogue World in September, admitting that she was "nervous about the idea of it, but once I had it on, everything else felt boring." She continued, "I was like, 'I'll have that photo for the rest of my baby's life.'"
