What Should I Do with My Wedding Dress...

Per my mom's suggestion, I decided to write about my wedding dress. Currently it is tightly sealed in a very large box up in our guest bedroom. After I said "I do," I thought about selling it, but was quickly dissuaded by my sister. "Don't you remember looking at mom's dress when we were little?" I do recall these moments. I enjoyed the time spent with my mom and siblings, but I was always very glad when my mom said "Don't feel like you have to wear this dress!" So, for sentimental reasons I kept my dress. I'm beginning to have second thoughts. I may be able to get a pretty chunk of cash for my dress...and the longer I wait....the less likely I will be able to sell it. It's BEAUTIFUL. I LOVED wearing it, but I was also very glad when it was time to take it off (sheesh...those dresses aren't made for comfort). So, readers....what should I do? Keep it or sell it? What have you (or your wife) done with your dress?
