Blake Lively can add fashion designer to her already impressive resume.

The 27-year-old former "Gossip Girl" is officially launching a fashion line called Rejoice. The line is part of a collaboration with her lifestyle website, Preserve, and Armour Vert, a green eco-chic fashion line that focuses on sustainability and has a zero-waste design philosophy.

Ryan Reynold's wife took to Instagram Tuesday to unveil her first piece, which was a dress made entirely of silk and featured an ivory tie-top and a billowing printed skirt. The "Champagne Dress" can be preordered on the Preserve website for $230.

"I may not be able to draw worth a lick, but I am proud of this dress I co-designed with Amour Vert for @preserve_us," she proudly captioned the snapshot of her dress. "You better send me pics if you buy it! I want to share your photos!! #PRSRV so I see it."

Lively followed up her post with another pic of herself and jewelry designer Ofira Sandberg wearing matching tropical print outfits, with the caption, "#FashionFaceOff with the only woman who can make me look like a toddler @ofirajewelz Which do you guys like: Dress or jumpsuit! I co-designed this collection too with the trusty Sam & Lavi."

She added, "I'm just boasting now because you guys fluffed me so much on the last post. Beware: don't feed the ducks flattery. It dangerously swells their ego. And tummies apparently. Someone pass the spans."

The "Natalie Jumpsuit" and the "Elisa Dress" also retail for $275 and $265 on Preserve. Currently, the "Age of Adaline" actress has over a dozen styles available on her Preserve website.
