The answer to that question is.... a lot less than you think.
(I'm really talking to the girls here. You guys aren't too bad in my experience although you may pick up a few ideas.)
You really don't need as much as you think you do. I found that it didn't matter how long I was going for, even for a year, I didn't need any more clothes than I needed for a week. The exception to that would be if your climate changes from say the heat of southern Spain to snow capped mountains of Canada. If that is what you are doing, then I would take what I needed for the place I was going first or longest and head straight to the charity shops, if they have any, or local markets when I needed clothes for change in climate.
Don't make the same mistakes I made.
