When my cousin T died, her widower asked her friends to come by and, if we weren't weirded out by it, to take any of her clothing that took our fancy before he sorted it out and gave it away to charity.
I wasn't weirded out - T was always beautifully put together, and for me wearing her clothing is a reminder of her style and her bright and bubbly personality - as well as her encouragement to me to push my limits in style. (I was pretty conservative in style until I hit about 30 and basically went IDGAF and wear more or less whatever I like.) So I took a couple of dresses that were not quite in my style, some jewellery, and a coat that was in a style that I particularly liked.
Today, T's widower is remarrying. A good woman, from what I can see, and trusting A's judgement of good character, and T was canvassing for a new wife for A as soon as she knew she was terminal. (I don't know if N was ever on T's radar, but they were friends at some point in the past.)
I guess what I'm wondering is whether it would be appropriate to wear "T's coat" to A and N's wedding today.
