Embarrassing car boot sale scenario: when you try on a fragile vintage dress, and the zip breaks. Do you then feel obliged to buy it regardless – and whether you really wanted it or not? Thankfully, the seller – who had been eagerly trying to zip me into it – very quickly said it was her fault and halved the price to £5 , and I did want this one. It is linen, has pretty embroidery and narrow lines with lacey cut-out details,, and is Spanish-made; 1960s style, but maybe newer. And I think I can persuade my mother to put a new zip in it. Hopefully, when not trying to put it on over a bulky T shirt, denim skirt and leggings, it might just be big enough.
