Specialty women’s apparel retailer LuLuLemon Athletica Inc. has launched Ivivva.com for U.S. shoppers. Ivivva, which rolled out online in Canada in the second quarter, offers dance and athletic apparel for girls.

Ivivva.com’s product lines include sport bras, tank tops, leotards, jackets, shorts, pants, skirts and accessories, along with seasonal products such as headbands and legwarmers.

The online store was designed to mirror Ivivva’s three stores in Canada, the company says. Web site features include individual product description pages, fabrics and features information, and large images that show product and fabric detail. The site also offers complementary ground shipping, and web customers can bring online purchases to any LuLuLemon location for free hemming.

Ivivva.com plans to host a Help Us Design section where guests can e-mail their feedback directly to Ivivva designers, the company says, and a blog that will feature inspirational content for dancers and athletes.

“We heard loud and clear from guests in our U.S. Lululemon stores that young girls across the United States are ready for Ivivva,” says Christine Day, CEO, LuLuLemon Athletica, No. 229 in the Internet Retailer Top 500 Guide.
