The next hot designer collaboration to land in Topshop stores comes from fashion's new darling and Brit knitwear designer Mark Fast. Fast made headlines last year when he used plus-size models on the catwalk which ruffled a few industry feathers. His mainline retails from a breathtakingly pricey £1200 (approximately AUD$2048) and upwards so it's great that Topshop are offering something more wallet-friendly. There are only five pieces in this capsule collection and FYI, prices are steeper than the regular Topshop merch. Click through to see more.
