I am getting an old dress altered and it got me thinking about keeping things around in our closets that no longer fit (take fit in whatever sense you wish). In these cases, do you throw out/donate the garment, save it for just in case, or get it altered? Does the type of clothing (pants/tops/dresses) factor in? Does the size (too small/too large/ too too small/too too large) matter? Sentimental value? What have your experiences been?
