I used to have only one green top. Recently, I expanded my "collection" with two other green tops from Target. I have worn them this winter with knowlege that springy apple green is not quite right in January and February.
I put one on today, even though I don't work someplace where people are jaunty about pinches to the green-less. I was not planning on going to the parade or any morning parties, even. I'm not in anyway that I know Celtic. I'm usually a bad sport when it comes to culturally-controlled dresscode.
The neckline was torn, though, a testament to the global economy, so I changed into all black and was done with it.
If you own a business, you can tell people what to wear.
