I brought the Single Button Magic Jacket up from the basement after I lost a little weight. Part of the Magic is that the bottom half doesn't ever have to touch, so you can still wear it though technically it's a size too small (and it is).
(And we all know we can make any jacket a "Single" Button Magic Jacket by just "forgetting" to button the bottom button. I believe I heard it became fashionable to leave the bottom button of one's waistcoat unbuttoned during the reign of Edward 7, because he, being fat, always "forgot.")
I pass this information along to you, children, because someday you too will be fat (yes, yes you will, unless you work out 5 hours a day like Cher). Find your Magic Jacket and treasure it, even though it is out of style.
