Can you believe this woman is considered a Plus-Size Model?

This woman does not look Plus-Size to me at all. I saw these ads for Marina Rinaldi inside O magazine, and thought wow what beautiful outfits. I had never heard of Marina Rinaldi before so I Googled the name.

I honestly was shocked to discover that Marina Rinaldi is the Plus-Size division of Italian designer Max Mara. This woman in the ad is supposed to be Plus-Size? Marina Rinaldi's sizes run from a 10-22 US, and the clothes can be found at upscale department stores like Bloomingdale's, Saks and Bergdorf Goodman. There are also Marina Rinaldi stores around the world.

They consider a size 10-12 Plus Size! Are you kidding me ?!?

If you look at the Saks Designer Apparel sizing chart a size 2 is a 24" waist which is the average waist size of your typical Victoria's Secret model. A size 10 is a 28" waist and a size 12 is a 29.5" waist which is ONLY 4-5.5" bigger than someone who is the width of a mannequin. Fashionistas, you are telling me that someone with a waist under 30" is still considered Plus-Size? I am seriously perplexed and horrified by this notion.

Do you all think this is crazy or is it just me?
