This week’s Instagram fashion star is adorable style blogger and merchandising intern Katherine Tabinowski (www.instagram.com/styletab). The 23-year-old Delaware native is new to Massachusetts, but isn’t new to searching out vintage fashion at secondhand stores. She’s still trying to find her way around Boston, but has no problem finding a good food truck or cat videos on YouTube. Think of her as Hingham’s answer to Zooey Deschanel. Time to find out what this new girl has to say for herself — and her pesky shopping addiction.
