I don't mind sharing my age. I am 41 and I've been carrying Coach off and on for the last 16 years. I got real serious about Coach after I started working there three months ago and I have given up most of my LV to carry only Coach.
I'm 22 years old and will be 23 in March. I haven't noticed an age average for Coach. But I have noticed that more young girls do own Coach but I think that is because it is a bit more affordable than other designers.
Turned 39 this month---have only been carrying Coach for 3-4 years---based on the comment that inspired this poll in the original post, I must be a late bloomer
