Two Sisters teen and tween boutique celebrated their grand opening last weekend in Greenville’s Powder Mill Square. Owner Kara Hebert greeted moms and daughters, who stopped by for their first look at a bevy of spring designs for girls between 1st and 8th grades. While young shoppers were excited about the trendy, hip clothes and accessories, they were equally enthusiastic about the “Report Card Reward Program” that rewards girls with various discounts based on their hard work and good marks at school. What’s more, young athletes who participate in any race sponsored by the Delaware Running Company can bring in their race bibs to receive a discount on any item in the store. “I am trying to help perpetuate and encourage tween girls to make strong, healthy choices in all aspects of their lives — not just in how they choose to dress,” said Hebert.
