Try to choose a shape that is the opposite of your body type. If you are tall and thin, look for a slouchy, rounded hobo bag to complement your figure. If you're short and voluptuous, play off opposites by choosing a handbag that is tall and rectangular or long and sleek (like a clutch).

In general, the rounder your figure, the more structured your bag should be. That doesn't mean that you have to carry a hard box around to counterbalance your womanly shape: rectangular or square silhouettes in soft leathers or fabrics will do the trick.

Some popular shapes:

Tote: An open-top bag with straps or handles.

Hobo bag: A crescent-shaped shoulder bag.

Duffle: Tall shoulder bag, often with an opening on top that can be made wider by loosening a tie.

Field bag: A flap-top shoulderbag with utility-type closure (buckles, snaps, etc).

Clutch: A small, handheld bag (frequently used for evening wear).

Satchel: A large, handheld bag.

Baguette: Long and rounded shoulder bag resembling the namesake French bread.

Messenger: A large, soft shoulder bag with long straps (can be worn across the body) and often, a flap over the top.

Cigar Box: A small, boxy, hard bag.

Pouch: A soft, small bag.

Kelly bag: A classic Hermes style named after Grace Kelly that is a large, structured handbag with distinctive hardware closures.

Scale:

While the shape should oppose your body type for maximum flattery, the size of the bag should be in proportion to your figure.

A woman who is 6 feet tall and a size 14 would look lost with a teensy hand-held bag. A petite size 0 would look overwhelmed by an enormous slouchy bag.

Close-fitting bags are a great look if you're svelte and want to show off cleavage; not so great if your arms and bust are large.

How to tell if a shoulderbag is right for you? Try on the bag. If it feels cramped under your arm and constantly hits your breast, it's not for you.

A shoulder bag's length (where the bottom of the bag hits your body) will accentuate whatever part of the body it rests near. For example, a shoulder bag that ends around the hips will play up your hip width (the eye is drawn to the bag).

Most women look great with a bag that hits mid-torso because it flatters the waist.

Tips for choosing a bag:

* Take time in a store to try on handbags in front of a mirror just like you would apparel.

* Don't be tempted by trendy shapes that don't suit your figure: there are plenty of great alternatives that will work.

* Think lifestyle when shopping for handbags: If you're toting diapers and graham crackers, an artsy vintage bag won't hold up.
