Join Charlie Gowans-Eglinton, Bethan Holt, Victoria Moss and Caroline Leaper in the studio: also on the agenda, royal rule-breaking at Ascot and the rise of designer homewares. Plus, what we’re excited about this week, from World Cup waistcoats to wild swimming.  Visit telegraph.co.uk/fashion-unzipped-podcast/ for more on these and other stories and email your questions and feedback to [email protected].
