Should Burberry's be focused on new brick-and-mortar stores, as new CEO Christopher Bailey did with the opening

Question:

Should Burberry's be focused on new brick-and-mortar stores, as new CEO Christopher Bailey did with the opening of Burberry's largest store, 121 Regent Street in London, or should they focus on more online sales worldwide? Are high-end products (clothing such as Burberry's) better sold in stores or online, or both?
