Samantha Brown Belt Bag sizing issue

Ordered two of these belt bags. I think there is a design issue or manufacturing spec issue as to sizing of the belt. I am a S or XS and ordered two of these belt bags. Adjusted the belt to the smallest setting and they fell right off my hips. How did these skinny hosts wear them on air?
Wanted to post review but the shipping status has been stuck in Packaging the entire week they have been in my home! Saw a plus size customer complaining they are not OS. Well they aren’t for small gals either. Samantha normally has great products. Disappointing.
