Jezebel and Its All Yoga Baby , recently wrote articles beating up Lululemon for not offering plus sized clothes. This issue is directly related to the "Why doesn't Yoga Journal have normal looking models" argument but I will focus on LuluLemon. It is simple. These companies are in business to make a profit.
The author of the Jezebel article was a size 18. I have been practicing yoga for about 11 years. It is extremely rare for me to see someone in a yoga class that is that size. The average body in a yoga class, from my observations, is between a size 6 and a size 10. All good businesses do market research and create products based on the market group that would most likely buy their products. If the average person attending a yoga class is a size 6, it would not make good business sense to create size 18 clothes. Many times, clothes that are below or above the average, wind up going in the bargain bin and the studios and stores make no money.
Then their is the discussion on the people they hire and the images in their advertising. Advertising has always been about selling a dream. My major was marketing. That is what people want to see and that is what works. Again these people are in the business of making money. They are trying to draw people into their store. Even plus sized stores use beautiful atypical girls. Take a look at these Lane Bryant, a plus sized store, ads? Seriously how often do you see women this beautiful and this well proportioned in your every day life?
They use this girl because she can sell some clothes. Because women want to imagine that they can look like her and be like her. She makes the clothes look good. Her beauty draws attention.
I totally get the argument for plus sized clothes and plus sized women in advertising but I also understand why a business would chose not to produce them or would use beautiful thin girls to advertise their products.
