9. Ed Sheeran at The 2015 Grammy Awards
The award shows give an extra challenge for musicians compared to movie actors. Musicians are free spirited and creative people who wear casual (if not eccentric) outfit both daily and during performances.
Ed Sheeran might not win any Grammy that night, but he did show up in style. Ed wore the classic suit with some twists to adjust his own style.
One of his tricks was to lose the blazer and put on some neat vast to keep the elegant look. He also added casual sneakers. He wore them for two reasons: they are more comfortable and they suit him more.
He showed off his tattoos (believe me, he has lots of them) on his arms by rolling the sleeves up a little. Just enough to keep it cool yet still formal.
