At the end of Netflix’s “To All the Boys I’ve Loved Before,” everything is pretty perfect. Lara Jean Song Covey (Lana Condor) and Peter Kavinsky (Noah Centineo) are in a relationship and all is right in the world. When we rejoin Lara Jean in the sequel, “To All the Boys: P.S. I Still Love You,” the picture is similarly rosy, with the protagonist getting ready for a date.

But for costume designer Lorraine Carson, it meant her character has changed. “She’s got a boyfriend,” she says. Along with that, Lara Jean has progressed emotionally and is expressing herself through her clothing and hair, “and that’s what I wanted to show on camera.”

Carson looked at Lara Jean’s silhouette, keeping the pleated skirts that she so often turned to in the first film, but this time, “we tailored her to be more body-conscious.” The designer’s approach was simple. She went for a look that was “vintage, eclectic, but fashion-forward.”

Lara Jean’s shoes alternated between penny loafers with a heel or penny loafers with tassels and her favorite Mary Janes.
