If you are planning to buy a handbag as a gift for your girlfriend, then you should know some tips about how to choose a handbag that fits your girlfriend. Try to choose a shape that is the opposite of her body type. If she is tall and thin, look for a slouchy, rounded hobo bag to compliment her figure. If she is short and voluptous, play off opposites by choosing a handbag that is tall and rectangular or long and sleek (like a clutch).
