Rent a wedding dress? Bridesmaid dress?

My poor wedding dress is in a bundle on the bottom of my guest room closet. I keep thinking I need to 'preserve it' and put it in a box, but the thing is just pitiful. I won't wear it again, my daughter (if I ever have one) won't wear it - let's be honest. I would have TOTALLY rented a dress - especially if I found one in the stores that I loved, knew the style fit me, anyway brides - I'm just saying...
