I had "the" dress shortly after we were engaged.
Mom asked me to help her find an outfit to wear for a wedding she was going to attend. I randomly ask her if she still has her wedding dress. When she replied yes, I asked her to bring it out so that I can try it on. She starts saying that she was very small back then, and she's not sure I'd be able to fit in it. I was a little insulted! I had been losing weight this year mostly because FI was losing weight (and looking good!). I knew I could fit into her dress! She found it, brought it down, and zipped me up. Yep, it fit! Mom loved seeing me in it. I model-walked for my dad, and he had this great big smile on his face. I go back to Mom and say "I would totally wear this if you'd let me alter it...you know, update the look." And she starts nodding. She asks me what I'd do, and I say that I would cut off the sleeves and make it into a sweetheart strapless gown. And she says "okay, let's do it."
When I get married next year, the dress will be 28 years old. I love that it's sooo vintage!
Wedding dress, check.
