To celebrate Saint Patrick’s Day and this thrifty fashion lovin’ girl’s concern for her budget along with the planet, I present this, my “ultimate green post.”

As reported at Things Your Grandmother Knew, eBay’s latest ad campaign includes promoting the eBay Green Team by pointing out how environmentally kind and ethical wearing previously owned clothing is: The greenest product is the one that already exists. And that certainly includes vintage fashions and accessories!

In the ad in the April issue of Marie Claire, eBay shares the following facts:

Choosing new-to-you leather shoes saves more energy than an average household uses in a day.

Buying a pre-loved silk dress saves 95% of the CO2 needed to make a new one.

Choosing a previously owned leather clutch saves as much energy as not watching TV for 3 days straight.

The facts may be new, but the principal probably isn’t news to vintage fashion lovers. The question is, do you think this will change buying habits?
