Besides paying for the traffic, i'd suggest you to create an account on all the major social media sites, where fashion is big. Those are instagram, pinterest and tumblr. You can either hire someone to build your accounts or you can do it yourself with specific bots or online tools, but you don't even need tools, just a little bit of free time to build the accounts manually.
Head over to the social media section of the forum for guidance, tips, best practices, latest limits and what not.
