After more than 20 years together, Grethen House and Netc are splitting up. No need to pick sides - the separation is amicable. Netc is moving down the block at 50th & France, to the former Stephanie's space near The Loft. Owner Nancy has a new partner as she starts contemplating scaling back her workload. They will open as Netc the first week of June with an expanded assortment of high-end shoes and accessories. Meanwhile, Grethen House is wasting no time filling the void with its own spin on shoes and accessories to complement the designer fashions that have made this boutique a destination for decades. From two proven vets like these, I say the more the merrier.
