I need a security system for my closet!

I have three sisters who live close....close enough to drive over and visit...a LOT.  They are my best friends and great fun and aside from the occasional catfight, it is wonderful.  The downside though is that we all pretty much wear the same size clothing.  The other day one of my sisters was lamenting the cost of dry-cleaning and telling me how she had FINALLY gotten all her stuff back from the cleaners, and "oh, you know what I found, your green Vince sweater".  HA!  I had completely forgotten about that sweater, but the second she mentioned it I remembered how great it was.  It isn't like I have so many clothes that I forget, but I have a bad memory and my sisters are crafty.  I have a Citizens sweatshirt that I adore and that I know my youngest sister wore home one day from house--6 months ago!  When I asked her about it she said, "oh, I don't have that"....I had to do an interrogation just to get her to admit she in fact DID have it!!  Another sister has a pair of cute orange tennis shoes that I loved, and she has worn them so much that honestly I feel like they aren't even mine anymore, they are molded to HER feet!!  Its like being in college when your roommates would borrow stuff except it isn't as convenient to get stuff back!  I've got to figure out some security system....maybe those theft tags you see at the mall :-), or a list of my "good stuff" so I don't forget what my good stuff is!!  Signed ME {lv}
