I got all the free clothes, just because they were free, as well.
I really would doubt this rumor being true (though they might take away some really old ones or something)- why they even added more free clothes with the last set of clothes they put into the wardrobe the other day!
Actually, I have a hat that was free a few days ago. I happened to be browsing the clothing again yesterday, and I see that the hat is no longer there. Or no longer free at least. I was only looking for free items. So it seems the free stuff may be, if not disappearing, being no longer free. At least for some items.
I read that if you have a subscription and take clothes that are "free to subscribers" you lose them when the subscription runs out (which my free beta one does in about a week). So I lose my 2 favorite outfits unless I pay
