I guess it depends, I usually own two or three big bags at any given moment, and so I choose my bag based on whet will complement my outfit best. I also tend to gravitated to different bags at different times of the year (summer colors vs winter formality etc). I buy a new bag probably once every three or for months, and get rid of my bags after I've had them for maybe two or three years? Its sort of a constant rotation I guess. I don't change my wallet as often because I'm lazy and hate transferring all my cards. I just bought a new Ralph Lauren wallet that's this beautiful laser cut leather, but I had my last wallet for three years I think?
