She and I are both a bit clueless about clothes. She's wearing the jumpsuit to a family party. We're going to get some gold sparkly sneakers and she'll also need something for her arms if it gets cold later. I thought a white denim jacket would be good, but she says no way. She'd prefer a cardigan. I can't find anything that might work. Looking on Asos, JL, M&S, Next etc. She'd be happy chucking her old hoodie on if it's cold, but I think on the night with everyone looking fancy she'll be pleased to have something nice.
Please help!
