Christopher Kane had a showroom presentation this season in his PR's studio. Simultaneously he released the lookbook images. This is not an isolated route to take for presenting collections now, mostly down to the cost of hosting a show or presentation at fashion week. But then Christopher Kane has a solid customer base and the retailers are behind him, so there may be no need for a catwalk show - it will sell regardless. Other designers still struggling to make sales in London's mens week have to show their presence with expensive endeavours, which would lead to press, but maybe not the sales.
