She鈥檚 one of your all-time favorite style icons, and now you can get a piece of Whitney Port鈥榮 incredible fashions for yourself. And the best part? It鈥檚 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 鈥減regnancy and childbirth safe for every mother.鈥

Starting today, September 15, you can choose from 60 of Port鈥檚 chicest pieces of clothing at all price points, from a pair of H&M printed pajama-style pants for $21.99, to Whitney鈥檚 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 鈥淪hop Her Closet鈥 series, following in the footsteps of Bachelorette Rachel Lindsay.

Since becoming a mom, Port says her style continues to evolve, and she鈥檚 rejecting the notion that new moms have to 鈥渂ounce back鈥 to a certain size after giving birth. 鈥淪ome people have been asking me what I鈥檓 doing to drop the baby weight. And I鈥檓 thinking, 鈥楲ay off people, I just made a human!'鈥 she says. 鈥淗onestly, I鈥檓 feeling more confident than ever, and I鈥檓 just rejecting the idea that I have to bounce back to a certain size. So, today I鈥檓 selling some of my pre-pregnancy clothes on to make room in my closet for clothes that fit my changing body and new lifestyle.鈥

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