Hey Vintage Vixen! Um …. what an amazing collection to inherit! I’m sorry, however, as it sounds like she may have passed away? ;-( Anyway, in my personal opinion the value of vintage is based on what the buyer will pay for it. So, it could be a bonafide made by Christian Dior himself piece but if the buyer doesn’t like the style, the “value” of the garment goes down …. despite collector’s worth. But to a collector, then yes that CD piece is worth a pretty penny. Then there is “vintage” that is simply a 100 percent cotton Bruce Springsteen concert tee, all sweaty and worn who knows where, but the nostalgia is so worth it that people spend $200+ on them. Personally, I go by style. I will pay more for something I LOVE. Are you planning on selling some of the pieces you inherited?
