- are they showing signs of wear?
- have the colors faded?
- do i need more color in my wardrobe?
- do they need mending?
- do they still fit properly? (note: casual does not equal sloppy!)
it's time to replace the dingy...the tired...and the "sight for sore eyes" from the closet...and when you do, add in some color (like the polo above) and print (plaid, paisley or whatever grabs you!)
and for the more adventurous...don't be afraid to mix prints in the same color family...
