To choose a handbag that will flatter you figure, choose a shape that is opposite your figure type. 

   For instance:  If you are tall and thin, choose a large, slouchy, rounded bag.  If you are shorter with a more rounded figure, look for a bag that is tall and rectangular or long and thin like a clutch.  As a general rule, the rounder your figure the more you need a bag with more structure such as a square or rectangular bag.

The size of the bag should correspond with your body size. Large women look good in large bags while small women need smaller bags.

A handbag's length will accentuate whatever part of the body it comes near.  If a shoulder bag hits at hip level it will accentuate your hip width. A bag that hits mid-torso is flattering for most women.
