Generally, large handbags, i.e., totes, are ideal for every day use, and smaller handbags, i.e., clutches, are great for special occasions and evenings.
Handbag (as opposed to purse) is the proper lingo.
Carry your handbag on your left so your right hand is free for socializing and greeting others.
Try not to place your handbag on the table. Instead, place it on an empty chair if available, or on the floor beside your chair (although superstition says not to place handbags on the floor!). If you have a clutch, put it behind you or next to you in your chair.
Keep your handbag tidy and organized.
