Getting away from a white or light colored tuxedo shirt is always a little dangerous. Certain staples shouldn't be mixed with. Light pink or blue is not bad, but again, you're just breaking from a classic.
At 15 I auditioned for 42nd Street in Australia. Dein Perry was in that show. I actually got the job but I couldn't do it because I was only 15. Legally I needed to have another 15-year-old to cover consecutive nights.
It's my memory, and what happened between that moment 10 or 15 years ago and now, there's a lot of gray area.
