Perhaps you can give us some insight into your preferences first, or specifically what you would need for your daily lifestyle. There are SO many great Chanel bags, if we don't really have any idea what your needs are, we might recommend that you buy something that doesn't really suit your taste or needs. For example, a classic flap is a GREAT choice for a first Chanel bag -but maybe you need to carry a LOT of stuff, and a tote would be more suitable for you.
Also, you can look in the reference library -there are many pictures and info from members (including prices) and you can get a better idea there of what you would like. HTH!
