Mimi Plange's Sophisticated Spring 2013 Fashion Week Collection

With her Spring/Summer 2013 showing, Mimi Plange proved that modestly can be sexy. Entitled "Tea With Mother," the pale floral collection "is a romantic celebration of ageless beauty."

Designer Mimi Plange.

"I was inspired by antique porcelain art and [raw] tea," says Plange, who worked in the fashion industry for 11 years before starting her own line.

Since the Ghana native debuted her first collection a few seasons ago, Mimi Pilange has sold particularly well in the Middle East. The first boutique to pick up her line is in Kuwait. She also sells exclusively to shops in Brooklyn and Austin. Even the First Lady Michelle Obama is a fan -- she wore one of Plange's ultra-feminine skirts for an appearance on "The View."

"Our customer is a baby boomer. She wants to look grown," she says. "There is a way to look young, but still look like a woman. I'm inspired by real women, who are put together. I like to see a woman looking grand."

To reflect her fondness for sophisticated ladies, the 34-year-old favors longer hemlines, intricate embroidery, exaggerated full sleeves and fluid pieces. Her materials of choice include silk crepe, silk organza, trapunto embroidered silk and lambskin. While they give a ladies who lunch nod to Upper East Side socialites, Plange's designs still feel fresh and modern.

Everything She Wants fawned over the collection's trapunto embroidered lambskin leather sheath "Jezebelle" dress; the "Cria" floral silk applique silk tee paired with the "Mayleen" multi-tier pleated button front skirt; and the "Stellah" pleated blouse with exaggerated sleeves paired with the "Edith" jute knot embroidered silk organza pencil skirt.

Prices range from $600 to $6000. For more information, check out the Mimi Plange website.
