Close enough...it's 635
I have a feeling it's like, half that.
In my experience, guys wear theirs until they are are falling apart. 
I was just thinking of that...I'd say it's closer to 1/4 or 1/8 of that.Weeeeird. That's a lot of panties. I wonder how many pairs a guy goes through in a lifetime? I have a feeling it's like, half that. In my experience, guys wear theirs until they are are falling apart.

hmm. that meams women buy around 10 per year ... that means almost one pair of pants a month.
That means that girls manage to wreck one pair a month? wow, guess us guys treat our underwear simply better ...
Uh, yeah...that's not even close to how it works. You think we have to wreck a pair of panties in order to have an excuse to buy more???? BAAAAAHAHAHAHAHAHA!
