Place to donate dress that is tax deductible?

I’ve heard of a place where you can donate a wedding dress and it is tax deductible. I do not remember the name, is anyone familiar with this? I have a Vera Wang dress that I bought at a sample sale more than a year ago, and I do not have the time to sell it so I remember I heard something about this.

Thanks in advance for your help.

Just an FYI--if you don't itemize your deductions on your taxes--it won't matter if you donate anything for a tax write-off. If you use a standard deduction--charitable contributions don't help

(not sure if you do or don't--but figured others might find the info useful)
