Time to “Bank”

My wife has a wonderful closet full to the brim with Dresses and skirts which she has never worn. They are all too large for her now. she has decided to dispose of them via door to door collectors from different Charities. I have my misgivings about these collectors and often wonder just how many of these items ever reach the intended destinations, so in conclusion I have decided that the will be safer in my keeping, You may think that this is selfish of me and I'm inclined to agree.....yum yum....My problem is where do I keep all these wonderful garments.....Any ideas as to where to conceal them would be so so very much appreciated...I may have to find a bigger bolthole....lol.
