She’s one of your all-time favorite style icons, and now you can get a piece of Whitney Port‘s incredible fashions for yourself. And the best part? It’s all for a good cause.

In an exclusive collaboration with thredUP, Port, who welcomed baby boy Sonny in July, is selling both pre-maternity and maternity clothing. One hundred percent of the proceeds go to Every Mother Counts, a non-profit organization started by supermodel Christy Turlington Burns, which aims to make “pregnancy and childbirth safe for every mother.”

Starting today, September 15, you can choose from 60 of Port’s chicest pieces of clothing at all price points, from a pair of H&M printed pajama-style pants for $21.99, to Whitney’s LOVE Binetti jacket for $322. For $280, mamas-to-be can snag the stunning Elizabeth and James floral kimono she wore to her baby shower earlier this summer, which might just be the perfect look for your baby shower too.

The Hills alum is the latest fashionista to lend her goods to the “Shop Her Closet” series, following in the footsteps of Bachelorette Rachel Lindsay.

Since becoming a mom, Port says her style continues to evolve, and she’s rejecting the notion that new moms have to “bounce back” to a certain size after giving birth. “Some people have been asking me what I’m doing to drop the baby weight. And I’m thinking, ‘Lay off people, I just made a human!'” she says. “Honestly, I’m feeling more confident than ever, and I’m just rejecting the idea that I have to bounce back to a certain size. So, today I’m selling some of my pre-pregnancy clothes on to make room in my closet for clothes that fit my changing body and new lifestyle.”

But since Port also has a closet chock full of stunning maternity wear, she adds, “I’m also selling some super cute clothes I wore throughout my pregnancy. I’m excited that the proceeds from this sale will benefit Every Mother Counts, and will match every dollar raised.”
