Nothing says summer better than a crisp, white cotton blouse.

Nothing says mass-transit traveler better, either.

The odds that your light-colored clothes will survive the commute unbesmirched? Slim to none. Try a smart stylist tip: Carry a big, white gummy eraser in your bag. Just like it does paper, it’ll erase dirt and cinder markings from your clothes. The bigger the better, since a good grip is essential. You can pick these life-savers up anywhere, but take heed: The Pink Pearl in your desk won’t do the job. It’ll get rid of the mark, but it’ll leave a pink smear in its place.

Consider this a quick, easy, and, best of all, portable way to keep your dry-cleaning bills to a minimum.

And to make sure you’re sending the right message.
