The skirt is BurdaStyle's girls' metallic skirt, which I made in denim. Simple enough to sew, provided you don't mind making up your own instructions as the ones provided are exceptionally brief (directions for sewing the fly were particularly unhelpful). I followed 'instructions' religiously when cutting the waistband but I'm sure it's meant to be significantly wider as it turned out too narrow for a decent-sized button, and it looks different from that shown in the pattern photograph. I would have redone it, but didn't have enough fabric as I was already using leftover scraps from a previous project. I wound up using a bar fastener in lieu of a button and also adding buttonhole elastic to the back section of the waist to ensure a good fit (a wise move, as it turned out).
R snatched the skirt from me the moment it was finished, which surprised me a bit, given that it lacks colour, glitter, decoration and cat motifs. The whole outfit looks quite grown-up compared to some most of her other clothes, but happily she's still a bubble-blowing little girl whose favourite food is fairy bread and who teaches a class of Beanie Boos in her bedroom every day after school.
