It makes sense that Michael Buble’s tour is sponsored exclusively by Nordstrom. He’s got the dapper look down. Hence, he’s an ideal candidate to help an upscale department store pimp their clothing. Nordstrom has gone as far as to create an online guide to picking the perfect outfit for a Buble concert. (Men even have the option to “Dress Like Michael.) Obviously, you can wear whatever you damn please to the Key Arena. But the folks at Nordstrom have a point. Sometimes, it’s fun to rock a look based on the musician you’re seeing; e.g.: gold lame hot pants at a Lady GaGa show, ’80s letterman jacket at a New Kids on the Block reunion concert. Indulge me here. What are you wearing for your date with a certain Canadian crooner tomorrow evening?
