This is a DOT bag, it is the medium sized, everyday bag that seems to work for most women.  This is the bag I make the most of, by farThis.  It is 7 inches tall,  10 inches across and 5 inches width.  It has a high quality magnetic strap and a metal frame that overlaps like an old fashioned Doctor's bag.  It is secure and very durable.
 
This bag was made from vintage coats.  The lining is barkcloth, the sun is surrounded with silk.
