Molly examines her shelf of special things at the back of Mack's stall. She chooses the bottle-top bowtie and remembers the day she got it. Kez has had another idea - a trash fashion range, and Bob is helping her by bringing in boxes of old clothes. She repays him with a 'waste coat' - a waistcoat made entirely out of stuff most people would throw away. Kez is sure that, with Bob wearing it around the Big Hub, it will be a great advert for her range. There's just one problem: Bob really doesn't like it. Over at the Kids Club, Ayesha is showing her mum's accessories to her friends. The kids are inspired and want to make their own. James has to try and find the right materials so asks Mack for help. Mack only has a box of broken toys, but James thinks they might work. Bob tries to dispose of the 'waste coat' when he thinks Kez isn't looking, but she sees him and is a little upset and takes it back. Bob feels awful and tells Molly what has happened. Molly has an idea - to put on a special 'trash' fashion show, featuring Kez's clothes, to make it up to her. Bob thinks it's brilliant and they get to work. James distracts Kez by asking her to help the kids make accessories out of the broken toys while everyone gets the fashion show ready. Later, the kids model Kez's designs, and she is delighted. When Molly realises there's no-one to model the 'waste coat', Bob steps onto the catwalk and struts his stuff. The trash fashion show is a huge success.
