Cover art for Evening Wear lyrics by Mindless Self Indulgence

I think this song is about an unpopular person now gaining a lot of popularity and losing their individuality on the way, getting sucked in to the rich lifestyle.

"Everybody wants to join the club Once you join the club, the innocence is gone"

You envy the popularity.. but once you have it, you become like them and the innocence has gone.

My Interpretation
