BTM, we moved to the NE 31 years ago from the SE - these are dresses which I had pre-DC (including one from when I was 22). I am not sure, tbh, if DD even knows that I have them hanging in my wardrobe, but she is very much a trousers girl and probably wouldn't want to wear them anyway. She has in her wardrobe a 1978 t-shirt which my DH brought back from his first visit to the US, so hoarding obviously runs in the family. I do remember her saying when she was about 7 and we were about to get a new washing machine "Can I have the old one in my bedroom, mum?" 
My habit of hoarding does come in quite useful, though - the DGC are playing with toys which belonged to their parents (I am looking forward to DD moving to her new house when she will be given the wooden cradle and desk which she had when she was pre-school; oh, and also her wedding dress which is hanging in my wardrobe!). We had also kept the DC's cot, but when we got it out from the loft for DGS the fastenings had gone missing, so we ended up throwing it away. I was also amazed to find baby clothes up there recently - I had no idea that I had been harbouring thoughts of DC3!
