If you are trying to dress environmentally friendly, one of the most important things to do is find out who made the clothing you are about to wear and how it was made.

Here is a list of questions suggested by The Ecologist that you should ask your retailer that will help ensure that the clothing is Fair Trade certified or at least made under humane conditions.

1. How much are the people producing the clothes you sell being paid? A living wage for workers should cover the cost of meeting a family’s basic needs in food and water, housing and energy, clothing, health care, transportation, education and childcare.

2. What hours do they work? Can the retailer demonstrate that workers are not subject to excessive overtime or bad terms of employment?

3. Can workers defend themselves? Are unions and collective bargaining allowed and encouraged in the factories where the clothes are made and packaged?
