Help! What Is This Song?

Ok, i was in the changing rooms at "Topshop" and a song came on which i just loved instantly.

However, i've forgotten the lyrics so can't find the song.

I know it said something about:

"i wear a shirt and pants because i like to look good on stage" or something like that. It seemed to be insulting women who wear nothing on stage??

I can't remember and it's driving me mad!!

Any help would be much appreciated!!
