The Story Behind The Concept

In early 2016, at the height of the Zika Virus scare, Sarah Pottharst received exciting news from her brother and his wife – she would be an aunt before the end of the year. The couple lives in Charleston, SC where the summers are sweltering and mosquitos unrelenting, so they wanted to take precautions against the virus. The mosquito-borne illness has been linked to many disturbing health effects, most notably as babies develop in the womb and in their early years.

Sarah’s sister-in-law asked her to design garments from insect-repellent fabric that would be appropriate for both work and social gatherings. Only camping and hiking apparel brands were using this fabric at the time. That discovery inspired Sarah to develop a fashionable clothing line for women who need mosquito protection in their everyday lives.

As Sarah combed through the maternity market to find inspiration in “crowd favorite” silhouettes, she discovered they were mostly designed for the second and third trimesters to accommodate a growing belly. Zika can affect women at all stages of pregnancy so she set out to create stylish designs that would adapt to a woman’s body and flatter her regardless of size.

As a result, Per Vigore’s womenswear pieces are truly transitional. They are expertly crafted to flatter expectant and new mothers. This unique quality places the line in a category of its own, bridging the gap between “Maternity” and “Ready to Wear” to provide all women style and protection.

What Makes Our Womenswear Unique?

Per Vigore’s clothing combines style + protection for an innovative line of clothing suitable for women at all stages of their life.

The United States Center for Disease Control and Prevention (CDC) recommends that women wear garments that cover the body and utilize an Environmental Protection Agency (EPA) approved insect repellent to prevent the contraction of insect-borne diseases. In Per Vigore, you will find both of these qualities.

Each piece in Per Vigore’s line is designed for maximum protection without sacrificing style. Our womenswear tops, bottoms and completer pieces mix and match with one another, acting as elegant wardrobe builders that also serve to protect.

Per Vigore also infuses Permethrin, an EPA-approved insect-repellent chemical, into our fashionable garments. Extensive research concluded that Permethrin is safe and poses no adverse health effects to any human when infused into clothing. In fact, Permethrin is 27-times below the EPA’s level of concern. Permethrin retains its full repellent potential for nearly 70 washes, and only thereafter, it will begin to diminish minimally.
