Harry Styles gave fans one simple style tip as he gears up for his highly anticipated Together, Together global residency tour. The singer, 31, suggested wearing "comfy shoes" to move and groove in when asked about his "dress code" during an interview with iHeartRadio on Friday, January 23. "Dancing shoes. I want you to dance, that's it. We'll all be in it together," he added. The former One Direction star is set to embark on a seven-city, 50-date tour beginning in May at Johan Cruyff Arena in Amsterdam with special guest Robyn.
